I was a PhD student at the chair of Modeling and Simulation (former ALMA Junior Research Group) from December 2009 until June 2014. From July 2014 to September 2015 I was employed as as system developer at Bosch SoftTec in Hildesheim. Since beginning of October 2015 I work as a project leader for big data topics at Audi AG in Ingolstadt.

My main research interests are :

  • Numerical steady-state analysis of stochastic hybrid systems,
  • sensitivity analysis and parameter estimation of biochemical systems,
  • retrival of geometric bounds for the steady state distributions of structured continuous time Markov chains (CTMC) with infinite state-space by the use of Lyapunov functions, as implemented e.g. in the Geobound tool,
  • deterministic timed automata (DTA) as a specification mechanism for CTMC,
  • and detecting oscillatory behavior in discrete stochastic models of chemical reaction networks.
