Research & Scholarship
My primary areas of research are diversification patterns in fishes and the evolution of fish anatomy. Focused in two areas: (1) the patterns of diversification and anatomical evolution of the livebearers, topminnows, and killifishes (known as cyprinodontiform fishes), and (2) deep-sea fish diversification and anatomical evolution.
Two current projects where students may be able to participate are:
Exploration of the evolutionary relationships of fossil killifishes from the western United States to answer the question “How and when did the North American killifishes and topminnows diversify, and how and when did the disjunct geographic distribution of western U.S. killifish and topminnows arise?”
Exploration of the anatomy of the visceral bioluminescent organs of the deep sea barracudinas and sabertooth fishes to answer the question “How anatomically do they generate bioluminescence and how many times has bioluminescence evolved in this group?”
