The neural crest offers a unique model system to study cell migration mechanisms during vertebrate embryogenesis since migrating cells are accessible to in vivo time-lapse imaging and manipulation. We recently discovered by single cell profiling that...

Adaptive time stepping methods for meta-stable dynamics of the Allen Cahn and Cahn Hilliard equations are investigated in the spatially continuous, semi-discrete setting. Predicted behaviour of the number of time steps with specified local error...

My research program is motivated by fascination with bird flight. My laboratory group uses a multi-disciplinary approach that includes biomechanics, physiology, and neuroscience to examine flight ability. Our current research is organized around two...

I will discuss joint work with Lior Silberman in which we describe the topology of spaces of representations of Baumslag-Solitar groups into complex reductive algebraic groups.

A Digraphical Regular Representation (DRR) for a group G is a directed graph whose full automorphism group is the regular representation of G. In 1981, Babai showed that with five small exceptions, there is at least one DRR for every finite group. A...

Uncertainty Quantification (UQ) is an increasingly popular subject in computational science and engineering, that deals with assessing the impact on the PDE solution of the uncertainty on the coefficients of the same PDE. Coefficients here is a term...

We propose, analyze and test Anderson-accelerated Picard iterations for solving the incompressible Navier-Stokes equations (NSE). Anderson acceleration has recently gained interest as a strategy to accelerate linear and nonlinear iterations, based on...

Many problems in science and engineering are described in terms of equilibrium shapes on which certain conditions are imposed and which separate regions where the solution may have different properties. A prototypical problem of this type involves...

Optimal transport (OT) problems, initiated by G. Monge 200 years ago and refined by L. Kantorovich in the 1940’s, provide --among other things-- a quantitative way for measuring correlations between probability distributions. Martingale optimal...

Insulin is an essential hormone that regulates nutrient homeostasis. Insufficient insulin results in diabetes, one of the most prevalent and costly diseases. Although the primary actions of insulin are to induce glucose uptake and metabolism in...
