I am a research scientist at the University of California, Los Angeles working with Rafail Ostrovsky. Prior to joining UCLA I was a postdoctoral researcher at the University of Maryland working with Jonathan Katz. I received my PhD from ETH Zurich under the supervision of Ueli Maurer.

My research interests include:


Professional Activities

I am organizing the Theoretical Computer Science and Cryptography Colloquium at UCLA. If you are interested in giving a talk contact me.
