Our research focuses on the functioning of lake ecosystems, especially on food web interactions and their implications on lake management, and on the connections between top-down and bottom-up regulators in the pelagic and littoral zones of lakes.

The studies bring new information on the mechanisms that regulate the productivity of freshwater lakes. The studies have shown, for instance, that many widely accepted theories describing the dynamics of lake food webs may not hold in special circumstances (e.g. clay-turbidity).

The studies are also important from lake management point of view. The food web structure of lakes regulates water quality, which again greatly affects the possibilities of recreational and domestic use of waters. In numerous lakes, the management and restoration efforts have been re-targeted based on our study results.
