Associate Professor at Institute of Mathematics. He has received his Master in Mathematics and Ph.D. in Applied mathematics at Comenius University, Bratislava in Slovakia. He also worked as a scientific project assistant at Johannes Kepler University in Linz. His research interests are in the field of dynamical systems (deterministic and stochastic differential, difference and integral equations) with applications in biology, medicine, ecology, and finance. He also deals with optimal designs of experiments, non-additive integration and information theory and its relation to statistical testing and stochastic approximation. He has published research articles in high-impacted international journals of mathematical and statistical sciences and is a referee of several international journals in the frame of pure and applied mathematics. He is giving lectures since 2011. Subjects are focused on Mathematical analysis, Differential and Integral equations, Numerical methods and Applied mathematics. He is a member of Union of Slovak Mathematicians and Physicists. He published more than 50 papers (42 registered in WOS or Scopus databases) and He registers more than 170 citations.
