We are a team of biologists studying the evolution of sexual reproduction in insects and spiders. We love the big picture and the little details. We strive to test theory by understanding mechanism. Research themes include sexual selection, sexual conflict, co-evolutionary dynamics, and life history evolution.

Current projects in the lab are focused on color use during courtship and foraging, co-evolution between visual systems and visual signals, and evolutionary dynamics between male seminal fluid proteins and the female reproductive tract. We are also committed to supporting science education and science literacy in Cincinnati and beyond, and have a number of ongoing projects with community partners.
