I'm Thomas Espitau - which is homophonic to Sπτ - a PhD student in Cryptography, working under the supervision of prof. Antoine Joux and prof. Pierre-Alain Fouque. I love maths, computer science, skiing and skateboarding. I'm also an enthusiastic Kenshi and Go player.


My research interests mostly lie in algorithmic number theory, especially in the theory of reduction of quadratic forms and the geometry of numbers. I'm moreover excited by the study and design of algorithms from lattice-based cryptography. I also like to spend time thinking of verification of probabilistic programs, trough the prism of logic and probabilistic couplings.

What's new ?

  • I'll be in Grenoble the 19/12 to present some work on reduction of real quadratic forms.
  • Our proof-of-concept of lattice reduction algorithms implemented using Interval Arithmetic is available. Learn more
