Ph.D. student specializing in Machine Learning and Computer Engineering.

I’m a member of the Adaptive Computing and Embedded Systems Lab in the Electrical and Computer Engineering Department at UC San Diego, advised by Professor Farinaz Koushanfar.

My research interests include machine learning, speech and natural language processing, statistical modeling, reinforcement learning, adversarial learning, systems security and vulnerability analysis of deep learning models.

I received my B.Sc. in Electrical Engineering from University of Massachusetts, Amherst and B.A in Physics from Mount Holyoke College in 2015 and 2014, respectively. Prior to pursuing my research interests in academia, I worked as an Applications Engineer at Global Foundries New York. I’m a recipient of Charles Lee Powell Foundation Fellowship.
