src Currently, I am a postdoc at the University of Graz in the group of Kristan Bredies. I work on designing and analyzing models in the context of crowd motion and cell biology, including membranes of crawling lymphocytes. In the case I study more specifically, this leads to gradient-flows which govern the evolution of rheologically nonhomogeneous curves on the plane. More generally, I am also interested in analysis of non linear PDEs, of drift-diffusion type in particular, just like the Keller and Segel model for chemotaxis. This also leads me to study some related functional inequalities.

Research

  • Modelling: biological membranes and crowd motion
  • Asymptotic behaviour for non linear diffusion
  • Mean-field models - Keller-Segel-type systems
  • Sharp functional inequalities
  • Numerical analysis
  • Some geometric analysis
