Research/Areas of Interest

My research seeks to integrate the fields of bat ecology, evolution and development (i.e. how ecolgical patterns of bats are constructed from evolutionary history and contemporary ontogeny). Current research involves the relationship of water resources to behavioral, populational and community ecology of bats in Coloradan, Botswana, South African and China. In addition, I study ontogeny in bats based upon investigations of skeletal development in juveniles as well as changes in functional ontogeny as they learn to fly as a surrogate for deciphering the evolution of flight in bats.
