Xin Chen

I am a PhD student in the group Theory of Hybrid Systems. My primary research interest lies in studying the behavior of hybrid dynamical systems, such as the reachability or stability analysis. I am also maintaining the tool Flow* which is a Taylor model-based analyzer for non-linear hybrid systems.

Research Interests

Currently I am working on a class of cyber-physical systems which can be modelized by hybrid automata, especially for the ones with non-linear continuous dynamics. My primal interests are as follows:

  • Theory of ordinary differential equations
  • Polynomial approximations for continuous functions
  • Computational geometry
  • Convex optimization
  • Statistical model checking on cyber-physical systems

Besides, I am also interested in

  • SAT checking
  • Mathematical logic and automata theory
  • Game theory
