Research

The overall goal of my research is to study the origin and conservation of biodiversity, with most work being done on freshwater fishes of North and South America. I do research in the field, in the laboratory, and at institutions such as zoos and natural history museums. The methods I use involve behavior, ecology, anatomy, physiology, and taxonomy and systematics. Some of my projects seek to better understand the evolution of social behavior, with a focus on mating systems such as monogamy and polygyny. My conservation-oriented research seeks to advance the social and psychological wellbeing of fishes held in captivity and to understand and control non-native introduced species.
