Lukas Burkhalter

I am fourth year Ph.D. student in the Applied Cryptography Group and the Privacy Preserving Systems Lab at ETH Zurich, where I am advised by Prof. Kenny Paterson, Prof. Friedemann Mattern, and Dr. Anwar Hithnawi. I graduated from ETH Zurich in 2017 with a Master of Science in Computer Science. Before that, I did my B.Sc. studies at ETH Zurich. I design and build privacy-preserving systems that use cryptography to give users more control on how their data is shared and processed.
