My research activities span diverse interests in the conservation, ecology and evolution of freshwater fishes, with particular emphasis on Eurasian salmonids. Currently, I use primarily genetic-based approaches to answer population genetic and phylogeographic questions on the current structure, diversity, and evolutionary history of salmonid fishes, such as European and Asian graylings (Thymallus sp.), whitefishes (Coregonus sp.), brown trout (Salmo trutta), soft-mouthed trout (Salmo obtusirostris), belvitca (Salmo ohridanus), lenok (Brachymystax lenok), and Danube salmon and Taimen (Hucho spp.), and Sahkalin taimen (Parahucho perryi). I have also worked with common carp (Cyprinus carpio), the endangered mudminnow Umbra krameri and the cyprinid genera Garra and Rutilus. While freshwater fish is my specialization I have cooperated in research on a variety of other organisms including salamanders, fruit flies, rabbits, stoneflies and otters.
