Research interests

My research work is primarily in theoretical physics. The emphasis is on achieving a thorough understanding of physically realistic model problems using analytical methods, numerical  investigations and (in some cases) simple experiments. I have worked on problems arising in solid-state physics, quantum mechanics, statistical physics, fluid dynamics, biophysics, genomics and astrophysics.
