Research Interests

My main interests are the proximate and ultimate mechanisms shaping body size evolution in invertebrates. I am focusing on the evolution of sexual size dimorphism in a family of flies (Diptera: Sepsidae) in which the direction of sexual size dimorphisms has been reversed multiply in close association with the strength of sexual selection on male body size. Currently, I am trying to uncover the developmental causes of body size differences between males and females and aim to reveal whether the multiple origins of reversed sexual size dimorphisms are based on the same or different sex-specific growth strategies. As side projects, I am also working on the ecology and distribution, as well as the evolution of mating systems of sepsid flies.
