Research Interests

Discrete and hybrid modeling of biological regulatory networks (have a look here)


logical modeling capturing essential structural and dynamical features of a given system based on qualitative data
discrete iteration analyzing complex behavior of regulatory networks using finite dynamical systems
graph theoretical and algebraic methods modularization and classification of regulatory networks based on structural and dynamical properties
hybrid modeling approaches discrete/continuous methods, stochastic aspects

Dynamics of complex and uniformly quasiregular mappings

My first love in mathematics: beautiful theorems, beautiful proofs, beautiful pictures (take a look)
