Research interest
My research focuses on examining behavioral responses—such as swimming activity, feeding patterns, personality traits, and cognitive abilities—in response to various biotic and abiotic factors. I apply this approach across different contexts, working closely with collaborators from other research fields. In partnership with evolutionary ecologists, I explore how ecological and evolutionary factors influence fish behavior, as well as how behavioral mechanisms might play a role in shaping biodiversity within and between populations. In the field of aquaculture, my goal is to gain insights into how fish adapt to farming environments and to assess welfare aspects (e.g., feed trials, farming practices) using behavior as a non-invasive assessment tool.
