Dr Thibault Congy


Department: Mathematics, Physics and Electrical Engineering

I obtained a PhD in Theoretical Physics in 2017 from the university of Paris-Saclay. Under the supervision of Prof. N. Pavloff, I investigated in my thesis nonlinear waves in Bose-Einstein condensates.
I then moved to Loughborough for a postdoc at the Mathematical Sciences department. I joined Northumbria University as a Research Fellow in 2018 and became a Lecturer in 2020.

My research is devoted dispersive hydrodynamics, a domain of Applied Mathematics and Physics concerned with fluid or fluid-like motion in which dissipation, e.g. viscosity, is negligible relative to wave dispersion.
