Research Interests

My research focuses on the evolution of morphology using dung beetles of the genus Onthophagus. Over 2,400 species have been described, most of which come in unique shapes and sizes. Specifically, I am interested in the evolution of insect genitalia.

Insect genitalia are not the obscure topic somebody might choose, but show unique morphological patterns when compared with other traits. For example, most insect genitalia grow essentially independently of body size, meaning that small males exhibit about the same sized genitalia as their larger conspecifics. Furthermore, most insect species can only be identified by the (male) genitalia. My research revolves around the latter:  why do insect genitalia diverge and what are, if any, the consequences of it?
