If it moves its potentially interesting! Im an aquatic ecologist with a behavioural ecological background. My approach to research often focuses on individual animal, or, most of the time, fish behavioural decisions, performance and success, and generally aims to address higher-order effects of these behavioural attributes. The higher-order processes include forager group formation and dynamics, spatio-temporal distributions of individuals in populations, impact of interference on individuals, populations and communities, as well as effects of piscivore behaviours on trophic cascades. Recent developments in my research interests focus also on the interplay between fish and their environment, such as the effects of lake water clarity on individual behaviours, causes and concequences of fish migration, more applied issues such as management considering the effects of angling on fish populations as well as the sustainable rebuilding of fish stocks, and the potential impacts of climate change on interactions among individuals and trophic levels in lake ecosystems. On the teaching side of things, Im involved in teaching courses on limnology, water management, aquatic ecology, marine ecology and fisheries ecology.
