Research Interests

I am senior research fellow at the Department of Biology, Lund University. The interest of my research group covers a wide range of theoretical and applied problems in ecology and evolution and we integrate mathematical modelling, experimental approaches and statistical analysis of observational data. Current work includes the study of phenology as a general problem in life history evolution, and how the timing of recurrent seasonal events is shaped by the dynamics of the biotic and abiotic environment. We are also interested in stochastic population dynamics of exploited populations, including the role of fisheries in generating fluctuations in fish stocks.
