Research Interests
I use tools from partial differential equations and probability to study a variety of problems. A few topics of current interest are the interaction between mixing and diffusion, and high dimensional sampling problems. Other topics I've worked on recently include anomalous diffusion, anomalous dissipation, BoseβEinstein condensation, coagulation, fluid mechanics, homogenization, the Kompaneets equation, mixing, Q-tensors, and residual diffusion.
