Profile

I am an applied mathematician with thirty years of research experience in mathematical ecology and ecological modelling. My research spans across a broad variety of problems in ecology and population dynamics with a particular emphasis on modelling complex multiscale environmental and ecological systems. I published four books and about 150 papers in peer-reviewed journals. My recent research on the effect of the global warming on the atmospheric oxygen where he discovered a new type of ecological catastrophe has been published in high-ranked scientific journals and highlighted by media around the world. In 2011-21 I was the Editor-in-Chief of Ecological Complexity (Elsevier); since 2020 I am the Section Editor-in-Chief “Mathematical Biology” of Mathematics (MDPI). I am also the founder and the scientific coordinator of the MPDE conference series.

Research

Applied dynamical systems in ecology & environment: coupling between biological and environmental processes multiscale models of agroecosystems in complex environments mathematical modelling of plankton dynamics Ecologically relevant diffusion-reaction systems: mechanisms of spatiotemporal self-organization in a system of interacting species pattern formation and chaos effects of stochastisity and noise exactly solvable diffusion-reaction models Models of animal movement & dispersal: random walks anomalous diffusion movement behaviour pattern formation Models of biological invasion: travelling population waves factors affecting the wave speed patterns of species spread different from travelling fronts (e.g. “patchy invasion”)
