Undergraduate Degree: B.S. Biology, Specialization in Environmental and Biological Conservation
Undergraduate University: University of Virginia
I am interested in the spatial ecology of
elasmobranch fishes (sharks and rays), particularly the mechanisms governing
movement phenomena, such as aggregation behavior, sexual segregation, seasonal
migration, navigation, and diel activity patterns. I am also interested in the biological and
ecological consequences (e.g., effects on population structure and mating
systems) and conservation implications of these phenomena (e.g., effectiveness
of existing and future reserves)
Social and non-social forces governing
aggregation behavior in the leopard shark (Triakis
