My academic interests in Biology have focused on the anatomy, evolution, and diversity of fishes. I am particularly interested in how the diversity of anatomical structures and physiologies in fish evolved. Until recently, most of my academic publications have focused on the anatomy and evolution of a group of fishes known as killifishes and livebearers (Order Cyprinodontiformes). My 16 peer-reviewed articles and book chapters that are focused on this group rely on fossil, anatomical, and/or DNA-sequence data to explore the evolution of reproductive modes, salinity tolerance, and biodiversity more generally in journals and volumes such as The Zoological Journal of the Linnean Society (2000), Copeia (1995, 1997, 2001, 2004), Fieldiana (2016), and Zootaxa (2017).
Recently my academic work has re-focused on using histological techniques in combination with many other sources of data to explore the evolution of specializations associated with living in the deep ocean in a range of groups of fishes. With bioluminescent-organ evolution studies published in 2015 on the naked barracudinas and 2018 on the glowbellies in the Journal of Morphology my research has now shifted to this new marine focus. I have always been interested in involving students in my research, to whom I can offer experience in marine biology, evolutionary biology, and/or anatomy that can benefit students with interests ranging from the environmental to the biomedical.
