Hi. I'm Amit N Subrahmanya.

I'm a Ph.D. student advised by Adrian Sandu, in the Computational Science Lab at the CS Department in Virginia Tech. I work on data assimilation, specifically, particle filters. My other interests include time stepping methods and machine learning for scientific computing.
