Anwar Hithnawi

I am an Ambizione research fellow at ETH Zurich where I lead the Privacy Preserving Systems Lab. My research focuses on data privacy, applied cryptography, and systems. I completed my Ph.D. in Computer Science at ETH Zurich. Upon graduating, I spent two wonderful years as a postdoc at UC Berkeley.
