About me

I graduated in Computational Engineering Science (RWTH Aachen University) and I am currently pursuing a Ph.D. degree in mathematics under the supervision of Prof. Dr. Manuel Torrilhon. Among different topics in applied math and (computational) physics, I am particularly interested in


  • Computational fluid dynamics
  • Rarefied gas dynamics
  • Kinetic theory
  • Finite element methods
  • Modeling with partial differential equations
