==Abstracts==<br />
<br />
'''9/23 Thomas Anderson:''' I'll talk a bit about potential theory as it is used today in the solution, via boundary integral equations / the boundary element method, of linear PDEs. These aren't only a numerical approach: I'll say a few words too about how they can be used to do analysis on problems. Then I may say a few things about volumetric potential theory: what are the problems there I've been thinking about, and application studies in mixing, for example, that they enable. Finally, I'll be happy to talk a bit about my experience so far in academia.<br />
<br />
'''9/30 Jeff Hammond:''' Jeff Hammond is a principal engineer with NVIDIA based in Helsinki, Finland, where his focus is developing better ways to write software for numerical algorithms. From 2014 to 2021, Jeff worked for Intel in Portland, Oregon; he started in the research organization and moved to the data center business group. Prior to that he worked for Argonne National Laboratory, first as a postdoc and then as a scientist in the supercomputing facility. Jeff was a graduate student at the University of Chicago and focused on developing open-source chemistry simulation software with Karol Kowalski at Pacific Northwest National Laboratory. He majored in chemistry and mathematics at the University of Washington. Details can be found on Jeff's home page: <nowiki>https://jeffhammond.github.io/</nowiki>. <br />
<br />
'''10/7 Jie Wang:''' We study distributionally robust optimization with Sinkhorn distance -- a variant of Wasserstein distance based on entropic regularization. We derive convex programming dual reformulations when the nominal distribution is an empirical distribution and a general distribution, respectively. Compared with Wasserstein DRO, it is computationally tractable for a larger class of loss functions, and its worst-case distribution is more reasonable. We propose an efficient stochastic mirror descent algorithm to solve the dual reformulation with provable convergence guarantees. Finally, we provide various numerical examples using both synthetic and real data to demonstrate its competitive performance and light computation cost. <br />
<br />
'''10/12 Matt Reuter:''' As children, most of us didn't know what we wanted to be "when we grew up," and, when asked, might have said, "an astronaut" or "a firefighter." I wanted to be a Ghost Buster and, pragmatically, wound up in computational chemistry and applied mathematics. In this talk, I'll discuss the winding path of my career from school to the national laboratory system to tenure-track faculty to teaching-line faculty. Along the way I’ll discuss my work exorcising (1) numerical ghosts from nanoscience research and (2) psychological ghosts from students when teaching mathematics. <br />
<br />
'''10/19 Ying Li:''' I will talk about my math background and my current role as a quantitative analytics specialist at Wells Fargo. Different types of quantitative analytics specialist at banking field will be generally introduced along with my opinions of the pros and cons for quantitative analytics jobs in financial area as a math student. I will also share my experience from academia to industry and the desired skill sets to be developed for looking for industry jobs. <br />
<br />
'''10/28 Yinling Zhang''': Discovering the underlying dynamics of complex systems from data is an important practical topic. In this paper, a new iterative learning algorithm for complex turbulent systems with partial observations is developed that alternates between identifying model structures, recovering unobserved variables, and estimating parameters. First, a causality-based learning approach is utilized for the sparse identification of model structures, which takes into account certain physics knowledge that is pre-learned from data. Next, a systematic nonlinear stochastic parameterization is built to characterize the time evolution of the unobserved variables. Furthermore, the localization of the state variable dependence and the physics constraints are incorporated into the learning procedure. Numerical experiments show that the new algorithm succeeds in identifying the model structure and providing suitable stochastic parameterizations for many complex nonlinear systems. <br />
<br />
'''11/4 Haley Kottler:''' Gaussian mixture models are an important class of models that arise in many applications. This talk will introduce these models, and talk about one method of parameter recovery from samples - the method of moments. I will also discuss some of the challenges that arise in implementation of this method in the multivariate case. <br />
<br />
'''11/11 Zinan Wang:''' In this talk, I will first introduce how to describe motions of a spatial serial robot and its singularities. Then I will talk about a new variable step method which rapidly calculates continuous kinematic paths that encounter singularities of a serial robot, especially how to control the step length. <br />
<br />
'''11/18 Parvathi Kooloth:''' One of the most important conservation laws in atmospheric and oceanic science is conservation of potential vorticity. The original derivation is approximately a century old, in the work of Rossby and Ertel, and it is related to the celebrated circulation theorems of Kelvin and Bjerknes. However, the laws apply to idealized fluids, and extensions to more realistic scenarios such as an atmosphere with moisture and phase changes have been problematic. In the talk, I'll describe a systematic approach based on Noether's theorem to arrive at the conservation principles for moist PV. <br />
<br />
'''12/6 Jenny Yeon:''' Finding a job is perhaps the most stressful part of the graduate school journey - at least this was the case for me. Magically, I ended up with multiple industry offers - from an engineering role to a scientist role. A huge success? Not really. The hiring managers placed me into the "entry-level," which means less salary plus many other things. This talk is about how I would have prepared differently so that I would have avoided a bunch of "entry-level" jobs. How can we make our time at "phd" also count toward the years of experience? <br />

Numerical experiments show that the new algorithm succeeds in identifying the model structure and providing suitable stochastic parameterizations for many complex nonlinear systems. <br />
<br />
'''11/4 Haley Kottler:''' Gaussian mixture models are an important class of models that arise in many applications. This talk will introduce these models, and talk about one method of parameter recovery from samples - the method of moments. I will also discuss some of the challenges that arise in implementation of this method in the multivariate case. <br />

'''9/23 Thomas Anderson:''' I'll talk a bit about potential theory as it is used today in the solution, via boundary integral equations / the boundary element method, of linear PDEs. These aren't only a numerical approach: I'll say a few words too about how they can be used to do analysis on problems. Then I may say a few things about volumetric potential theory: what are the problems there I've been thinking about, and application studies in mixing, for example, that they enable. Finally, I'll be happy to talk a bit about my experience so far in academia.<br />
<br />
'''9/30 Jeff Hammond:''' Jeff Hammond is a principal engineer with NVIDIA based in Helsinki, Finland, where his focus is developing better ways to write software for numerical algorithms. From 2014 to 2021, Jeff worked for Intel in Portland, Oregon; he started in the research organization and moved to the data center business group. Prior to that he worked for Argonne National Laboratory, first as a postdoc and then as a scientist in the supercomputing facility. Jeff was a graduate student at the University of Chicago and focused on developing open-source chemistry simulation software with Karol Kowalski at Pacific Northwest National Laboratory. He majored in chemistry and mathematics at the University of Washington. Details can be found on Jeff's home page: <nowiki>https://jeffhammond.github.io/</nowiki>. <br />
<br />
'''10/7 Jie Wang:''' We study distributionally robust optimization with Sinkhorn distance -- a variant of Wasserstein distance based on entropic regularization. We derive convex programming dual reformulations when the nominal distribution is an empirical distribution and a general distribution, respectively. Compared with Wasserstein DRO, it is computationally tractable for a larger class of loss functions, and its worst-case distribution is more reasonable. We propose an efficient stochastic mirror descent algorithm to solve the dual reformulation with provable convergence guarantees. Finally, we provide various numerical examples using both synthetic and real data to demonstrate its competitive performance and light computation cost. <br />
<br />
'''10/12 Matt Reuter:''' As children, most of us didn't know what we wanted to be "when we grew up," and, when asked, might have said, "an astronaut" or "a firefighter." I wanted to be a Ghost Buster and, pragmatically, wound up in computational chemistry and applied mathematics. In this talk, I'll discuss the winding path of my career from school to the national laboratory system to tenure-track faculty to teaching-line faculty. Along the way I’ll discuss my work exorcising (1) numerical ghosts from nanoscience research and (2) psychological ghosts from students when teaching mathematics. <br />

'''9/23 Thomas Anderson:''' I'll talk a bit about potential theory as it is used today in the solution, via boundary integral equations / the boundary element method, of linear PDEs. These aren't only a numerical approach: I'll say a few words too about how they can be used to do analysis on problems. Then I may say a few things about volumetric potential theory: what are the problems there I've been thinking about, and application studies in mixing, for example, that they enable. Finally, I'll be happy to talk a bit about my experience so far in academia.<br />

'''9/30 Jeff Hammond:''' Jeff Hammond is a principal engineer with NVIDIA based in Helsinki, Finland, where his focus is developing better ways to write software for numerical algorithms. From 2014 to 2021, Jeff worked for Intel in Portland, Oregon; he started in the research organization and moved to the data center business group. Prior to that he worked for Argonne National Laboratory, first as a postdoc and then as a scientist in the supercomputing facility. Jeff was a graduate student at the University of Chicago and focused on developing open-source chemistry simulation software with Karol Kowalski at Pacific Northwest National Laboratory. He majored in chemistry and mathematics at the University of Washington. Details can be found on Jeff's home page: <nowiki>https://jeffhammond.github.io/</nowiki>. <br />

=== Feb 7, Keith Rush ===<br />
I'll talk about the kind of work I do today, the way I got here, and any insight I can give for someone hoping to pursue a similar path. I'll also discuss some of the things I've learned, and some of the advantages and disadvantages a mathematician has in the machine learning and computer science world. We'll be sure to have a freewheeling discussion and a good time :).<br />
<br />
=== Feb 14, Shawn Mittal ===<br />
A short snapshot of what the data science industry looks like followed by some lessons learned on what makes an effective data scientist.<br />
<br />
=== Feb 21,Brandon Boggess ===<br />
I will be talking about software development and the transition from academic research to enterprise engineering.<br />
<br />
=== Feb 28, Shi Chen ===<br />
The underlying physics of the same system is different when the system is described at different scales. In classical mechanics, the motion of a particle is governed by the Newton's second law, while in quantum mechanics the status of a particle follows the Schrödinger equation. The classical mechanics and the quantum mechanics are two sides of the same coin, but how can we formally connect the two disparate systems? In this talk, I will introduce the Wigner transform, which is the only known method that seamlessly connects the classical and quantum systems as the Planck constant vanishes. I will keep everything basic and briefly introduce some applications of the Wigner transform to direct and inverse wave type problems.<br />
<br />
=== Mar 7, Tom Edwards ===<br />
I will talk about comparisons between small and big companies.<br />
<br />
=== Mar 14, Aidan Howells ===<br />
We'll learn what a chemical reaction network is, with a bunch of real-world examples. There are a number of ways to model these networks as objects of mathematical study, two of which will be discussed. We'll end with a few of the questions mathematicians try to answer about these models, to give you some of the flavor of the field.<br />
<br />
=== Apr 4, Eza Enkhtaivan ===<br />
In recent years, Reinforcement Learning has found great success in many areas of AI research ranging from research on self-driving cars to achieving superhuman level performance in MOBA games such as Dota 2, Starcraft (Open AI) or Chess and Go (AlphaGo Zero). I will talk about the mathematical framework of Reinforcement Learning and also briefly about its applications in computational neuroscience/psychiatry as well. <br />
<br />
=== Apr 11, Micky Steinberg ===<br />
I will talk about a what a typical work day looks like for me, and some advice for getting a similar job coming from academia.<br />

== Abstracts ==<br />
<br />
=== Feb 7, Keith Rush ===<br />
I'll talk about the kind of work I do today, the way I got here, and any insight I can give for someone hoping to pursue a similar path. I'll also discuss some of the things I've learned, and some of the advantages and disadvantages a mathematician has in the machine learning and computer science world. We'll be sure to have a freewheeling discussion and a good time :).<br />
<br />
=== Feb 14, Shawn Mittal ===<br />
A short snapshot of what the data science industry looks like followed by some lessons learned on what makes an effective data scientist.<br />
<br />
=== Feb 21,Brandon Boggess ===<br />
I will be talking about software development and the transition from academic research to enterprise engineering.<br />
<br />
=== Feb 28, Shi Chen ===<br />
The underlying physics of the same system is different when the system is described at different scales. In classical mechanics, the motion of a particle is governed by the Newton's second law, while in quantum mechanics the status of a particle follows the Schrödinger equation. The classical mechanics and the quantum mechanics are two sides of the same coin, but how can we formally connect the two disparate systems? In this talk, I will introduce the Wigner transform, which is the only known method that seamlessly connects the classical and quantum systems as the Planck constant vanishes. I will keep everything basic and briefly introduce some applications of the Wigner transform to direct and inverse wave type problems.<br />
<br />
=== Mar 7, Tom Edwards ===<br />
I will talk about comparisons between small and big companies.<br />
<br />
=== Mar 14, Aidan Howells ===<br />
We'll learn what a chemical reaction network is, with a bunch of real-world examples. There are a number of ways to model these networks as objects of mathematical study, two of which will be discussed. We'll end with a few of the questions mathematicians try to answer about these models, to give you some of the flavor of the field.<br />
<br />
=== Apr 4, Eza Enkhtaivan ===<br />
In recent years, Reinforcement Learning has found great success in many areas of AI research ranging from research on self-driving cars to achieving superhuman level performance in MOBA games such as Dota 2, Starcraft (Open AI) or Chess and Go (AlphaGo Zero). I will talk about the mathematical framework of Reinforcement Learning and also briefly about its applications in computational neuroscience/psychiatry as well. <br />

I'll talk about the kind of work I do today, the way I got here, and any insight I can give for someone hoping to pursue a similar path. I'll also discuss some of the things I've learned, and some of the advantages and disadvantages a mathematician has in the machine learning and computer science world. We'll be sure to have a freewheeling discussion and a good time :).<br />

Polynomial systems arise naturally in many applications in engineering and the sciences. This talk will outline classes of homotopy continuation algorithms used to solve them. I will then describe ways in which structures such as irreducibility, symmetry and sparsity can be used to improve computational speed. The efficacy of these algorithms will be demonstrated on systems in power systems engineering, statistics and optimization<br />
<br />
<br />
=== Sept 27, Wil Cocke ===<br />
I mostly work as a software developer with an emphasis on data science projects dealing with various Command specific projects. The data science life-cycle is fairly consistent across industries: collect, clean, explore, model, interpret, and repeat with a goal of providing insight to the organization. During my talk, I will share some lessons learned for mathematicians interested in transitioning to software development/ data science. <br />
<br />
<br />
=== Oct 4, Anjali Nair ===<br />
The phonon transport equation is used to model heat conduction in solid materials. I will talk about how we use it to solve an inverse problem to reconstruct the thermal reflection coefficient at an interface. This takes the framework of a PDE constrained optimization problem, and I will also mention the stochastic methods used to solve it.<br />
<br />

A vertical Lagrangian coordinate has been used in global climate models for nearly two decades and has several advantages over other discretizations, including reducing the dimensionality of the physical problem. As the Lagrangian surfaces deform over time, it is necessary to accurately and conservatively remap the vertical Lagrangian coordinate back to a fixed Eulerian coordinate. A popular choice of remapping algorithm is the piecewise parabolic method, a modified version of which is used in the atmospheric component of the Department of Energy's Energy Exascale Earth System Model. However, this version of the remapping algorithm creates unwanted noise at the model top and planetary surface for several standard test cases. We explore four alternative modifications to the algorithm and show that the most accurate of these eliminates this noise. <br />

During the course of a PhD, students typically enter a proverbial `coal mine’ to extract new information about one or more problems, and in the process become a domain expert in a small niche of the technical and scientific world. Upon leaving the academy, unless one lands a job in their niche domain, much of their problem- and domain-specific knowledge is no longer essential. However, mathematics is broad and general, arguably the most general of all scientific disciplines. This fact alone is a mathematician’s greatest asset and ‘leg-up’ when entering the industrial workforce. In this talk, I will discuss some details of my work, both inside and outside of the academy, with the goal of highlighting the skills and concepts that have been the most general and transferable for me. For example, my academic work on hyperbolic inverse problems helped me learn signal processing concepts I now use daily, while my studies on polycrystalline grain growth pushed me to learn thermodynamics, which translated well to the information theory concepts I now utilize. I will also give you some idea of my current day-to-day responsibilities, and close with my thoughts and suggestions on job searches.<br />

I work as a researcher at MITRE, a company that manages R&D contracts (FFRDCs) with federal agencies. I am nominally a machine learning engineer, but my department supports a diverse array of initiatives with the IRS. In this talk I'll give an overview of the FFRDC space, give a sketch of what I work on and how I spend my time, and share my thoughts about navigating the transition from academia to industry.<br />
<br />

After graduating from the UW, I ventured into the world of trading. My first job was at Virtu, a high-frequency market-maker, and currently I work at Auros, which is a high-frequency trading firm that focuses on cryptocurrencies. During the talk, I will give an overview of the industry, job market, and interview process from the perspective of a "quant". Then I will describe the day-to-day work and give a high-level description of typical projects. <br />

The solution to the diffusion equation is known to converge exponentially to its steady state, and the rate is given by the spectral gap of the elliptic operator. Using variational techniques, we will maximize the spectral gap over choices of spatially dependent diffusion functions. Using this characterization, we can obtain bounds on the optimal rate of convergence.<br />

Boltzmann equation is a fundamental kinetic equation that describes the dynamics of dilute gas. In this talk I will focus on the boundary value problem of the Boltzmann equation and introduce the Cercignani-Lampis boundary, which is a physical boundary that describes the intermediate reflection law between diffuse reflection and specular reflection. <br />

=== Sept 20, Julia Lindberg===<br />
Polynomial systems arise naturally in many applications in engineering and the sciences. This talk will outline classes of homotopy continuation algorithms used to solve them. I will then describe ways in which structures such as irreducibility, symmetry and sparsity can be used to improve computational speed. The efficacy of these algorithms will be demonstrated on systems in power systems engineering, statistics and optimization<br />
<br />
<br />
=== Sept 27, Wil Cocke ===<br />
I mostly work as a software developer with an emphasis on data science projects dealing with various Command specific projects. The data science life-cycle is fairly consistent across industries: collect, clean, explore, model, interpret, and repeat with a goal of providing insight to the organization. During my talk, I will share some lessons learned for mathematicians interested in transitioning to software development/ data science. <br />
<br />
<br />
=== Oct 4, Anjali Nair ===<br />
The phonon transport equation is used to model heat conduction in solid materials. I will talk about how we use it to solve an inverse problem to reconstruct the thermal reflection coefficient at an interface. This takes the framework of a PDE constrained optimization problem, and I will also mention the stochastic methods used to solve it.<br />
<br />
<br />
=== Oct 18, Jason Torchinsky ===<br />
A vertical Lagrangian coordinate has been used in global climate models for nearly two decades and has several advantages over other discretizations, including reducing the dimensionality of the physical problem. As the Lagrangian surfaces deform over time, it is necessary to accurately and conservatively remap the vertical Lagrangian coordinate back to a fixed Eulerian coordinate. A popular choice of remapping algorithm is the piecewise parabolic method, a modified version of which is used in the atmospheric component of the Department of Energy's Energy Exascale Earth System Model. However, this version of the remapping algorithm creates unwanted noise at the model top and planetary surface for several standard test cases. We explore four alternative modifications to the algorithm and show that the most accurate of these eliminates this noise. <br />
<br />

During the course of a PhD, students typically enter a proverbial `coal mine’ to extract new information about one or more problems, and in the process become a domain expert in a small niche of the technical and scientific world. Upon leaving the academy, unless one lands a job in their niche domain, much of their problem- and domain-specific knowledge is no longer essential. However, mathematics is broad and general, arguably the most general of all scientific disciplines. This fact alone is a mathematician’s greatest asset and ‘leg-up’ when entering the industrial workforce. In this talk, I will discuss some details of my work, both inside and outside of the academy, with the goal of highlighting the skills and concepts that have been the most general and transferable for me. For example, my academic work on hyperbolic inverse problems helped me learn signal processing concepts I now use daily, while my studies on polycrystalline grain growth pushed me to learn thermodynamics, which translated well to the information theory concepts I now utilize. I will also give you some idea of my current day-to-day responsibilities, and close with my thoughts and suggestions on job searches.<br />
<br />
<br />

I work as a researcher at MITRE, a company that manages R&D contracts (FFRDCs) with federal agencies. I am nominally a machine learning engineer, but my department supports a diverse array of initiatives with the IRS. In this talk I'll give an overview of the FFRDC space, give a sketch of what I work on and how I spend my time, and share my thoughts about navigating the transition from academia to industry.<br />

After graduating from the UW, I ventured into the world of trading. My first job was at Virtu, a high-frequency market-maker, and currently I work at Auros, which is a high-frequency trading firm that focuses on cryptocurrencies. During the talk, I will give an overview of the industry, job market, and interview process from the perspective of a "quant". Then I will describe the day-to-day work and give a high-level description of typical projects. <br />
<br />

The solution to the diffusion equation is known to converge exponentially to its steady state, and the rate is given by the spectral gap of the elliptic operator. Using variational techniques, we will maximize the spectral gap over choices of spatially dependent diffusion functions. Using this characterization, we can obtain bounds on the optimal rate of convergence.<br />

=== Sept 20, Julia Lindberg===<br />
Polynomial systems arise naturally in many applications in engineering and the sciences. This talk will outline classes of homotopy continuation algorithms used to solve them. I will then describe ways in which structures such as irreducibility, symmetry and sparsity can be used to improve computational speed. The efficacy of these algorithms will be demonstrated on systems in power systems engineering, statistics and optimization<br />
<br />

=== Sept 27, Wil Cocke ===<br />
I mostly work as a software developer with an emphasis on data science projects dealing with various Command specific projects. The data science life-cycle is fairly consistent across industries: collect, clean, explore, model, interpret, and repeat with a goal of providing insight to the organization. During my talk, I will share some lessons learned for mathematicians interested in transitioning to software development/ data science. <br />

The phonon transport equation is used to model heat conduction in solid materials. I will talk about how we use it to solve an inverse problem to reconstruct the thermal reflection coefficient at an interface. This takes the framework of a PDE constrained optimization problem, and I will also mention the stochastic methods used to solve it.<br />

A vertical Lagrangian coordinate has been used in global climate models for nearly two decades and has several advantages over other discretizations, including reducing the dimensionality of the physical problem. As the Lagrangian surfaces deform over time, it is necessary to accurately and conservatively remap the vertical Lagrangian coordinate back to a fixed Eulerian coordinate. A popular choice of remapping algorithm is the piecewise parabolic method, a modified version of which is used in the atmospheric component of the Department of Energy's Energy Exascale Earth System Model. However, this version of the remapping algorithm creates unwanted noise at the model top and planetary surface for several standard test cases. We explore four alternative modifications to the algorithm and show that the most accurate of these eliminates this noise. <br />

During the course of a PhD, students typically enter a proverbial `coal mine’ to extract new information about one or more problems, and in the process become a domain expert in a small niche of the technical and scientific world. Upon leaving the academy, unless one lands a job in their niche domain, much of their problem- and domain-specific knowledge is no longer essential. However, mathematics is broad and general, arguably the most general of all scientific disciplines. This fact alone is a mathematician’s greatest asset and ‘leg-up’ when entering the industrial workforce. In this talk, I will discuss some details of my work, both inside and outside of the academy, with the goal of highlighting the skills and concepts that have been the most general and transferable for me. For example, my academic work on hyperbolic inverse problems helped me learn signal processing concepts I now use daily, while my studies on polycrystalline grain growth pushed me to learn thermodynamics, which translated well to the information theory concepts I now utilize. I will also give you some idea of my current day-to-day responsibilities, and close with my thoughts and suggestions on job searches.<br />

The solution to the diffusion equation is known to converge exponentially to its steady state, and the rate is given by the spectral gap of the elliptic operator. Using variational techniques, we will maximize the spectral gap over choices of spatially dependent diffusion functions. Using this characterization, we can obtain bounds on the optimal rate of convergence.<br />

== Abstracts ==<br />
<br />
=== Sept 20, Julia Lindberg===<br />
Polynomial systems arise naturally in many applications in engineering and the sciences. This talk will outline classes of homotopy continuation algorithms used to solve them. I will then describe ways in which structures such as irreducibility, symmetry and sparsity can be used to improve computational speed. The efficacy of these algorithms will be demonstrated on systems in power systems engineering, statistics and optimization<br />
<br />
<br />
=== Sept 27, Wil Cocke ===<br />
I mostly work as a software developer with an emphasis on data science projects dealing with various Command specific projects. The data science life-cycle is fairly consistent across industries: collect, clean, explore, model, interpret, and repeat with a goal of providing insight to the organization. During my talk, I will share some lessons learned for mathematicians interested in transitioning to software development/ data science. <br />
<br />
<br />
=== Oct 4, Anjali Nair ===<br />
The phonon transport equation is used to model heat conduction in solid materials. I will talk about how we use it to solve an inverse problem to reconstruct the thermal reflection coefficient at an interface. This takes the framework of a PDE constrained optimization problem, and I will also mention the stochastic methods used to solve it.<br />
<br />
=== Oct 18, Jason Torchinsky ===<br />
A vertical Lagrangian coordinate has been used in global climate models for nearly two decades and has several advantages over other discretizations, including reducing the dimensionality of the physical problem. As the Lagrangian surfaces deform over time, it is necessary to accurately and conservatively remap the vertical Lagrangian coordinate back to a fixed Eulerian coordinate. A popular choice of remapping algorithm is the piecewise parabolic method, a modified version of which is used in the atmospheric component of the Department of Energy's Energy Exascale Earth System Model. However, this version of the remapping algorithm creates unwanted noise at the model top and planetary surface for several standard test cases. We explore four alternative modifications to the algorithm and show that the most accurate of these eliminates this noise. <br />

=== Sept 20, Julia Lindberg===<br />
Polynomial systems arise naturally in many applications in engineering and the sciences. This talk will outline classes of homotopy continuation algorithms used to solve them. I will then describe ways in which structures such as irreducibility, symmetry and sparsity can be used to improve computational speed. The efficacy of these algorithms will be demonstrated on systems in power systems engineering, statistics and optimization<br />
<br />
<br />
=== Sept 27, Wil Cocke ===<br />
I mostly work as a software developer with an emphasis on data science projects dealing with various Command specific projects. The data science life-cycle is fairly consistent across industries: collect, clean, explore, model, interpret, and repeat with a goal of providing insight to the organization. During my talk, I will share some lessons learned for mathematicians interested in transitioning to software development/ data science. <br />

'''Phase separation in the advective Cahn--Hilliard equation'''<br />
<br />
The Cahn--Hilliard equation is a classic model of phase separation in binary mixtures that exhibits spontaneous coarsening of the phases. We study the Cahn--Hilliard equation with an imposed advection term in order to model the stirring and eventual mixing of the phases. The main result is that if the imposed advection is sufficiently mixing then no phase separation occurs, and the solution instead converges exponentially to a homogeneous mixed state. The mixing effectiveness of the imposed drift is quantified in terms of the dissipation time of the associated advection-hyperdiffusion equation, and we produce examples of velocity fields with a small dissipation time. We also study the relationship between this quantity and the dissipation time of the standard advection-diffusion equation.<br />
<br />
<br />
=== 10/14, Yuchen Dong (WPI) ===<br />
'''A Half-order Numerical Scheme for Nonlinear SDEs with one-sided Lipschitz Drift and Hölder Continuous Diffusion Coefficients'''<br />
<br />
We consider positivity-preserving explicit schemes for one-dimensional nonlinear stochastic differential<br />
equations. The drift coefficients satisfy the one-sided Lipschitz condition, and the diffusion coefficients<br />
are Hölder continuous. To control the fast growth of moments of solutions, we introduce several explicit<br />
schemes including the tamed and truncated Euler schemes. The fundamental idea is to guarantee the<br />
non-negativity of solutions. The proofs rely on the boundedness for negative moments and exponential of<br />
negative moments. We present several numerical schemes for a modified Cox-Ingersoll-Ross model and a<br />
two-factor Heston model and demonstrate their half-order convergence rate.<br />
<br />
<br />
=== 10/28, Evan Sorensen (math) ===<br />
''' Unsupervised data classification via Bayesian inference'''<br />
<br />
Bayesian inference is a way of “updating” our current state of knowledge given some data. In this talk, I will discuss how one can use Bayesian inference to classify data into separate groups. Particularly, I will discuss an application of this to outlier detection in contamination control within semiconductor manufacturing. Time permitting, I will talk about some computational tools for these models.<br />

'''Pandemic Model with Asymptomatic Viral Carriers and Health Policy '''<br />
<br />
By October 13, 2020, the total number of COVID-19 confirmed cases had been 37,880,040 with 1,081,857 death in the world. The speed, range and influence of this virus exceed any pandemic in history. To find reasons of this incredible fast spread, we introduce asymptomatic category into a SEIR pandemic model. Based on published data of Italy, we calibrated exposed rates of COVID-19 in this model and then simulated the spread of COVID-19 for different asymptomatic rates. To measure the effects of different types of public health policies on this pandemic, we construct a pandemic model including health policies. By the simulation of this model, we provide feasible suggestions of containment to regulators. <br />
