My research centers on the study of chiropteran diversity and the processes that create it (speciation), maintain it in intact ecosystems (community ecology), and preserve it in the face of human disturbance (conservation biology). My work focuses primarily on the insectivorous bats of South East Asia; a species-rich group that occurs as highly diverse assemblages in the threatened rainforests of the region. Indeed, by the end of this century, we estimate that more than a fifth of South East Asia's bats will be globally extinct
