Doreen Riepel

Postdoctoral Researcher

UC San Diego


I am a postdoctoral researcher at UC San Diego working with Mihir Bellare. Before that, I completed my PhD in the research group of Eike Kiltz at Ruhr University Bochum (RUB), Germany, in the DFG Cluster of Excellence “Cyber Security in the Age of Large-Scale Adversaries“ (CASA).

I am interested in public-key cryptography and in particular in provable security. My research focuses on the design and analysis of cryptographic protocols.

I am lucky to have worked with inspiring researchers on the topic of (password) authenticated key exchange in several collaborations. In Summer 2021 I did a virtual internship at NTT Research mentored by Hoeteck Wee working on attribute-based encryption. We finally met in person during my stay at UC Berkeley in Spring 2022, where I visited the Crypto group of Sanjam Garg.
