I'm primarily interested in studying behaviour and ecology of larger mammals. So far my main focus was on the effects that large predators have on their prey and the interspecific interactions among large carnivores in areas where they coexist. I have done most of my work on Eurasian lynx, leopard, snow leopard, brown bear, grey wolf, and golden jackal, focusing primarily on their ecology, conservation and conflicts with people. To lesser extent I'm participating in research on cheetahs, black-backed jackals, Alpine chamois, red deer, ravens and raptors, reptiles, and ecology of terrestrial scavengers.
