Nathan Manohar

I am a Research Scientist in Cryptography, Security, and Privacy and a member of the Cryptography Research Group at the IBM T.J. Watson Research Center. My main research interests are cryptography, computer security, and, more broadly, theoretical computer science. I am particularly interested in fully homomorphic encryption, secure multi-party computation, and functional encryption.

I recently received my PhD in Computer Science from UCLA, where I was very fortunate to be advised by Amit Sahai. I received a bachelor's degree in Computer Science and Mathematics and a master's degree in Computer Science from Harvard University in 2016.

In my spare time, I enjoy playing violin and piano. As a PhD student, I played violin in the UCLA Symphony. I also like to spend time with my cat, Mary, who shares similar interests.
