I'm an Assistant Professor of Electrical Engineering at the City College of New York. I'm also a member of the doctoral faculty of computer science at the CUNY Graduate Center. My research group, the Spacelab, studies computer security and privacy, with an emphasis on providing guarantees for users' everyday systems. I received my PhD in computer science from Johns Hopkins University while studying under my advisor Avi Rubin. Those interested can peruse my curriculum vitae (CV). My pronouns are he/him.
Outside of the lab, you can find me trying my hand at photography and going on road trips.
I'm looking for a PhD student to join my research group! If you are interested in working with me, check out this page!
