Jérôme Govinden

I’m a final‑year PhD candidate at TU Darmstadt (Germany), under the supervision of Jean Paul Degabriele. My research centers around symmetric-key cryptography, particularly on the efficient design, analysis, and implementation of provably secure schemes with real-world applications.

In Fall 2024, I visited the Cryptography Group at the University of Washington, hosted by Stefano Tessaro. Previously, I was a research intern in the Cryptography Research Center of TII (UAE) and in the LIP6 Computer Science Laboratory (France). I hold a Master degree in Mathematics (Paris Cité University) and Computer Science (Sorbonne University).

You can find me on linkedin, and check out my CV and publications.
