Multiple Sclerosis (MS) is an autoimmune diseases that affects the central nervous system (CNS). It can lead to inflammation, neurodegeneration and physical or cognitive disability. To date, no cure for MS exists, but medications are available to...

The Cremona dimension of a finite group G is the minimal dimension of a rationally connected variety which admits a faithful action of G. In this talk, based on joint work with Giulio Bresciani and Angelo Vistoli, I will discuss new lower bounds on...

Sensing is a universal task in science and engineering. Downstream tasks from sensing include learning dynamical models, inferring full state estimates of a system (system identification), control decisions, and forecasting. These tasks are...

I will talk about a unification of two bounded height results around abelian varieties. The first is Silverman’s specialization theorem, which states for an abelian scheme A/C with no fixed part over a curve C, that the set of points on C where the...

We will discuss a class of ideals in a polynomial ring studied by Mark Haiman in his work on the Hilbert scheme of points and discuss how they are related to homology of affine Springer fibers, Khovanov-Rozansky homology of links, and to the ORS...

A central question in quantum chaos is how classical chaotic dynamics influence quantum behavior. On compact Riemannian manifolds, pure quantum states correspond to Laplacian eigenfunctions. The quantum unique ergodicity (QUE) conjecture of Rudnick...

Given a connected finite graph $G$, an integer-valued function $f$ on $V(G)$ is called $M$-Lipschitz if the value of $f$ changes by at most $M$ along the edges of $G$. In 2013, Peled, Samotij, and Yehudayoff showed that random $M$-Lipschitz functions...

Let G be a split reductive group. For X a projective G-homogeneous variety, there is a description of the decomposition of the Chow motive of X (Chernousov-Gille-Merkurjev, Brosnan). It is also known that these varieties satisfy the so-called Rost...

In this talk I'll give an overview of the mathematical side of the last eight years of my career as a software engineer at Google. This splits into two parts: writing software to automate the planning and management of Google's data centers as part...

In this talk, we present two algorithms associated with Tucker tensor format. The first is to obtain the Tucker tensor based on a new cross approximation we developed, called Cross^2-DEIM. This method samples a few fibers (proportionate to the multi...
