Florian Méhats
Professor in Applied Mathematics
Sopra Steria and Ravel Technologies, on leave from the University of Rennes
Biography
I am currently a research associate at the startup Ravel Technologies and an expert engineer in cryptography and applied mathematics at Sopra Steria, on leave from my position of Professor in applied mathematics in the University of Rennes. My research interests are homomorphic cryptography, machine learning/AI, mathematical and numerical modeling of physics (modeling of interacting particles, with applications to plasma physics, nanoelectronics and astrophysics). I am also interested in the advanced use of cryptography for Data Centric Security.
Interests
- Homomorphic cryptography
- Data Centric Security
- Machine learning and deep learning
- Mathematical and numerical modeling
- Partial Differential Equations (kinetic equations)
- Quantum physics, plasma physics, kinetic models for gravitation
