Entropic optimal transport has received a lot of attention in recent years and has become a popular framework for computational optimal transport thanks to the Sinkhorn scaling algorithm. In this talk, I will discuss the multi-marginal case which...

Cells in tissue can communicate short-range via direct contact, and long-range via diffusive signals. In addition, another class of cell-cell communication is by long, thin cellular protrusions that are ~100 microns in length and ~100 nanometers in...

A measured geodesic lamination on a hyperbolic surface encodes the horizontal trajectory structure of certain quadratic differentials. Thurston’s earthquake flow along such a lamination induces a dynamical system on the moduli space of hyperbolic...

To initiate movement, cells need to form a well-defined "front" and "rear" through the process of cellular polarization. Polarization is a crucial process involved in embryonic development and cell motility and it is not yet well understood...

Abstract: We consider a stochastic bistable two-species generalized Lotka-Volterra model of the microbiome and use it as a testbed to analytically and numerically explore the role of direct (e.g., fecal microbiota transplantation) and indirect (e.g...

Cell division is a vital mechanism for cell proliferation, but it often breaks its symmetry during animal development. Symmetry-breaking of cell division, such as the orientation of the cell division axis and asymmetry of daughter cell sizes...

Cellular polarization plays a critical during cellular differentiation, development, and cellular migration through the establishment of a long-lived cell-front and cell-rear. Although mechanisms of polarization vary across cells types, some common...

Graphs with no odd circuits are well understood. In 1992, Maffray characterized all graphs whose odd circuits only have size three. Oxley and Wetzler generalized this result to binary matroids in 2016. We give a complete characterization of all...

What does mathematics, materials science, biology and quantum information science have in common? It turns out, there are many connections worth exploring. I this talk, I will focus on graphs and random walks, starting from the classical mathematical...

There are various iterative approaches for solving unconstrained optimization problems. Between them, the non-monotone technique is a popular approach for improving the iterative algorithms in optimization. The non-monotone technique not only can...
