Cryptology & Privacy, PhD Student

Lena Heimberger is a PhD Student at Graz University of Technology, advised by Prof. Christian Rechberger. Her main research interests are designing and implementing low-level privacy-preserving primitives, especially OPRFs, and on how to translate them to a post-quantum setting. Her research interests include
  • mathematical cryptography, namely cool cryptography built from algebra
  • scalable and privacy-preserving cryptography, especially considering tradeoffs like bandwidth and parallelization. I currently work on both Private Information Retrieval and Oblivoius Pseudorandom Functions.
  • distributed computing, especially large-scale networks and federation, as well as messaging
  • as well as the legal aspects of the above, it would be nice to have a legislative ground to enforce privacy.
If you are a student looking for a thesis, project, or internship. I usually have some topic ideas that are in an early stage of development. If you are curious about any of the topics above, I'm happy to hear from you! Independently, I am always happy to hear from students regardless. If you think I can help you with something, you would like to discuss a topic further or just want to go to lunch and talk about university things, do write me.
