About

My research at the Maryland Cybersecurity Center (MC2) focuses on computer security and applied cryptography, with a specific emphasis on technologies, systems and theory providing secure computations in the cloud. Before joining UMD, I spent two years at UC Berkeley as a postdoctoral researcher, working with Dawn Song. Before Berkeley, I graduated with a PhD in Computer Science from Brown University, where my advisor was Roberto Tamassia.

I am always looking for bright and self-motivated students that wish to do research on computer security and applied cryptography. Feel free to contact me if you are interested.

My research is partially supported by the National Science Foundation, the National Institute of Standards and Technology, the National Security Agency, Google, Yahoo!, and Amazon.
