I am interested in the ecology, population genetics, evolution and management of primarily coastal marine animals. My research group works on topics spanning from the spatial and temporal population structure in teleosts and elasmobranchs to the conservation genetics of marine, freshwater and terrestrial species. Main current research areas include the genetics of sex-changing fish, the application of interdisciplinary approaches to stock identification, population connectivity in deep sea habitats, the role of hybridization in evolutionary and conservation biology, and the interrelationships between human societies and the exploitation of marine resources.
