Research Interests

My research interests are in the area of scientific computing, with a focus on computational partial differential equations and variational problems. Specific applications include plasma physics, solid-mechanics, liquid crystals and other complex fluid and electromagnetic problems. I am interested in both physical modeling as well as numerical computation using various finite-element methods and multigrid.

Here is a list of my Publications. and here are some "cool" movies of my (past) research.


Together with Xiaozhe Hu (Tufts) and Ludmil Zikatanov (Penn State), I am one of the authors of the HAZmath: A Simple Finite Element, Graph, and Solver Library, which provides basic finite element and graph routines.
PhD Students

Current Students
A list of the PhD students that I have advised or co-advised in the past is found on the Mathematics Genealogy Project.
Computational and Applied Mathematics Seminar

Each semester, I co-organize a research meeting/seminar with graduate students and faculty on computational and applied mathematics.
Most of the meetings are informal, but occasionally we have an invited speaker. See website for more details.
