This is my personal website! Welcome.

About Me

I am a third-year PhD student in the Computer Science department at Cornell University, advised by Tom Ristenpart. I'm located at the Cornell Tech campus in NYC.

Research

My research is in theoretical and applied cryptography. Currently, I am focusing on cryptography for cloud security applications. I'm also interested in lattice cryptography, primitives, cryptography engineering, and constructing protocols that do cool stuff.

My non-technical interests include censorship, privacy, legal and ethical issues related to information security, and the intersection of technology and society.

My research is supported in part by a 2017 NSF Graduate Research Fellowship.

Bio

I did my undergrad at Indiana University, where I majored in Math and Computer Science. After graduating, I worked for two and a half years at Skyhigh Networks as a cryptography engineer. I left in August of 2015 to start grad school at Cornell.
