Research Interests
My research focuses on the influence of secondary sexual characteristics on social perceptions, with an emphasis on mating-related contexts. In particular, I examine the influence of vocal and facial traits on perceptions such as attractiveness, trustworthiness, infidelity, and jealousy. My approach is informed by interdisciplinary perspectives from social and evolutionary psychology, psycholinguistics, and behavioural economics.
