My background is in statistical ecology (multivariate analyses, statistical modelling, study design, use and misuse of statistical methods and concepts), and my interests in ecology range from demography to ecosystem dynamics. How are life history traits of "fast" vs "slow" species shaped by environmental variability? How do seasonality influence trophic interactions and food web dynamics? How does climate change affects different trophic levels and ecosystem dynamics? I am particularly interested in species, communities and ecosystems of cold regions (arctic and alpine), which are characterized by strong seasonality, large environmental variability and strong climate signals.
