Profile picture of Lennart Oldenburg

Hello, I'm Lennart Oldenburg.

Since very recently, I am a PhD student in the COSIC group at KU Leuven, under supervision of Prof. Claudia Díaz. I obtained my M.Sc. in Computer Science from the Technische Universität Berlin. During my studies, I was lucky to spend one academic year at the University of California, Santa Cruz.

My research interests lie in the fields of Privacy-Enhancing Technologies and Distributed Systems. Specifically, I am curious about communicating anonymously and securely over unreliable and untrusted infrastructure, fault tolerance of large-scale distributed systems, cryptography and privacy in the online age, consistency of distributed data, and reaching consensus under different fault models.

I enjoy thinking about science, engineering, politics, and sustainability. Sometimes, my thoughts end up in text or code, for example in papers and software.
