Eliad Tsfadia
I am a Postdoctoral Fellow in the Department of Computer Science at Georgetown University, hosted by Prof. Kobbi Nissim. My research is supported in part by the Fulbright Program.
I have completed my Ph.D. in the School of Computer Science at Tel-Aviv University, where I was fortune to be advised by Prof. Iftach Haitner. I was also an intern researcher at Google Research - Israel, where I was fortune to work with Prof. Edith Cohen, Prof. Haim Kaplan, Prof. Yishay Mansour and Dr. Uri Stemmer.
My main research interests are Data Privacy and Cryptography.
