About Me

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 co-advised by 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 build systems that use cryptography to give users more control on how their data is shared and processed. Selected recent work includes: (i) TimeCrypt, a time-series storage that enables efficient confidential query processing coupled with user-enforceable data sharing, (ii) Zeph, a system that enforces a user's privacy preferences in streaming data applications.

Student Projects

Interested students in conducting bachelor/master thesis or a lab project in one of the following described projects can either send me an email or just drop by my office for a coffee to discuss further details. I am always looking for motivated and interested students who are ambitious about participating in ongoing research work.
