Abstracts
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.
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: https://jeffhammond.github.io/.
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.
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.
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.
