I am a postdoctoral research assistant in the field of applied mathematics in the research group of Prof. Ansgar Jüngel at the Vienna University of Technology.  My research is on partial differential equations and their applications in biology, physics, and chemistry. My focus is on the analysis, modeling and derivation of cross-diffusion in biological systems and multi-species kinetic models, moreover, I am interested in bridging PDE-techniques with probabilistic methods.

Research interests:

  • Entropy methods for diffusive systems
  • Cross diffusion in biological systems
  • Kinetic and diffusive multi-species systems
  • Hypocoercivity in kinetic equations
  • Interactions between kinetic and diffusive PDEs and probability
  • Uncertainty quantification
