Hi! I'm a second year PhD student in CSE at the University of Michigan, Ann Arbor. My research interest lies in the intersection of software systems and deep learning, with a recent focus on energy consumption. I lead the ML Energy initiative. I am fortunate to have Professor Mosharaf Chowdhury as my advisor.
