Anand U. Oza

I am interested in fluid mechanics and nonlinear dynamics, with applications to soft matter physics and biology. My research utilizes a combination of analytical techniques and numerical simulations, and I collaborate with experimentalists whenever possible. I am a part of the Complex Flows and Soft Matter (CFSM) Group.
