Aparna Gupte

I am a third-year PhD student in the Theory of Computation group at MIT, where I am fortunate to be advised by Vinod Vaikuntanathan. I'm interested cryptography and quantum computation. Before starting my PhD, I received my B.S. in computer science and mathematics, also from MIT. As an undergraduate, I was lucky to be mentored by Vinod Vaikuntanathan and Ankur Moitra.
