The main research interests of our group are the evolution and mechanisms underlying sociality and social behavior, we study bees as a model. To study these fascinating and intricate phenomena we integrate analyses at different levels, from molecular to social. In recent years, one of our main research focuses has been the interplay between circadian rhythms and social behavior ("sociochronobiology") but we also study additional important sociobiological processes such as size-related division of labor in bumblebees, the social evolution of juvenile hormone signaling, the interplay between sleep and social behavior, and the involvement of non-coding RNA and RNA editing in behavioral plasticity.

I investigate the biological underpinnings of human social behavior. Specifically, I'm interested in the role of neurohypophysial hormones, sex hormones, and cortisol in regulating human cooperative, aggressive, and competitive behaviors.
