Crypto Lab   Research    Teaching     Professional Activities    Students & Visitors     Biography

I am a cryptography researcher. Much of my work is on the foundations of cryptography, and as such I fit right in with our Theory Group. I also work on practical aspects and applications of cryptography, and am a member of our Systems Security Center. Additionally, I'm interested in connections between cryptography and other areas such as complexity theory, information theory, and machine learning. Example areas I've worked on include secure computation, private search, non-malleable codes, leakage and tamper resilient cryptography, and strong public key encryption.

The webpage for my group, the Crypto Lab, has our publications, as well as the latest news from my group, including new papers in preprint form. You can also check out my dblp and Google Scholar pages, or find my older papers (up to 2011) here.

If you want to work with me, please start by reading my information for prospective students and visitors.
