Abstract: "I will discuss several topics of my current research, which involves applications of topology and partial differential equations. First, we'll see how ideas from braids and mapping class groups can be used to investigate the behavior of dynamical systems as well as characterize braiding of actual textiles. Nest, we'll examine how the mixing of fluids can be studied via PDEs, and some connections to probability theory. Finally, I'll discuss probabilistic problems for swimming microorganisms, such as dispersion and consumption of resources." | |||

Abstract: A tridiagonal pair is a linear algebraic object that appears | |||
in many subjects, such as | |||
(i) Combinatorics (Q-polynomial graphs); | |||
(ii) Lie theory (sl2, affine sl2, tetrahedron algebra); | |||
(iii) Quantum groups (Uqsl2, affine Uqsl2, q-tetrahedron algebra); | |||
(iv) Physics (Onsager algebra, q-Onsager algebra); | |||
(v) Special functions (q-Racah polynomials etc from the Askey scheme of orthogonal polynomials); | |||
(vi) Representation theory (the universal Askey-Wilson algebra, DAHA of type (C1V, C1). | |||
We will describe some main facts about tridiagonal pairs, and discuss some | |||
of the above connections. The talk is nontechnical and meant for a | |||
wide audience. | |||

Title: '''Fluid-structure interactions, from biolocomotion and active suspensions to liquid crystals''' | |||
Abstract: I will discuss a few problems in the interactions of simple/complex fluids and immersed deformable structures, ranging from the evolution of locomotion on the planet to the dynamics and self-assembly of soft, active matter. I will show how the development of novel numerical techniques can be used alongside classical methods of applied mathematics to study the coupled nonlinear PDEs that describe these exciting physical systems, and point to a number of open problems in these fields. | |||

Title: '''Curve shortening in the plane and in space.''' | |||
Abstract: Curve shortening is one of the simplest geometric evolution equations like Mean Curvature Flow, Ricci Flow, Yang-Mills flow, harmonic map flow, Willmore flow.

Abstract: In Mathematics in general, and Analysis in particular, one strategy for solving a problem is to begin by understanding what a counter-example would look like. In this talk, we will apply a quantitative version of this approach to prove two endpoint results, one for a Fourier Restriction operator and one for an averaging operator.

In this talk, we will apply a quantitative version of this approach to prove two endpoint results, one for a Fourier Restriction operator and one for an averaging operator. The latter is joint work with Christ, Dendrinos, and Street.
