Dr. Mary Ann Ottinger is a Professor Emeritus in the Department of Biology and Biochemistry at the University of Houston in Houston, Texas in the United States. Previously, she was Professor in the Department Animal and Avian Sciences at University of Maryland, College Park. Dr. Ottinger received her PhD in Behavioral Neuroendocrinology from the University of Maryland. Her research incorporates interdisciplinary and comparative biology approaches to understand the impacts of environmental chemicals, especially endocrine disruptors (EDCs) on the development of endocrine and behavioral components of reproduction, neuroendocrine system function, and the comparative biology of aging. Her studies have focused on a spectrum of species, ranging from birds to non-human primates, providing expertise in translational studies across model systems. Dr. Cullen K. Geiselman holds a BA in Environmental Science and Policy from Duke University and an MA and PhD in Ecology and Evolutionary Biology from Columbia University. Her research catalogues ecological interactions among organisms, specifically seed dispersal and pollination by bats. This work led to her coauthoring a book with botanists from the New York Botanical Garden entitled Seed Dispersal by Bats in the Neotropics. In addition to her ecological research, she chairs the board and is the acting director of a foundation funding healthcare initiatives in the greater Houston area where she works with healthcare providers to expand medical and behavioral healthcare to the underserved.
