I'm currently working on highorder methods for solving fluidstructure interaction problems. The fluid, modeled using the compressible NavierStokes equations, is generally discretized usign a highorder discontinous Galerkin arbitrary Lagrangian Eulerian (DGALE) method. A variety of structures have been investigated including rigid airfoils, nonlinear membranes, and thin hyperelastic structures.

I was an officer in the Mathematics Graduate Student Association from 2008—2010. I was the MGSA appointee to the department's Computer Committee for the 20082009 school year. In Fall 2008 I surveyed other graduate students in the department and wrote a report outlining the status of the current computing infrastructure.
In 2008 I helped run Many Cheerful Facts, a series of weekly talks given by graduate students and aimed at a general mathematics audience.
I'm one of the delegates from the Mathematics Department to the Graduate Assembly, the graduate student government at University of California, Berkeley. I formerly chaired the Environmental Sustainability Committee and Technology Committee. I currently chair the Communications Committee.
In October 2009 I was appointed by Councilmember Jesse Arreguin (Berkeley, District 4) to the City of Berkeley Transportation Commission.
