There is a phone in my office (703-993-1463) but email is a better way to reach me.

About Me:

My research interests are in differential equations, existence and stability of traveling waves and pattern formation. Before coming to Mason, I completed my Ph.D. at Boston University and was a postdoc at the University of Minnesota.

Outside of mathematics, I play ultimate frisbee, hike, and spend time with my lovely wife and son.
