Biography

Dr. Jorge A. Ahumada, Conservation International-Center for Biodiversity Outcomes Professor of Practice, is the Executive Director for Tropical Ecology Assessment and Monitoring Network (TEAM).  Jorge received his degree in Biology at Universidad de Los Andes in Bogotá, Colombia and obtained his Ph.D. in Ecology and Evolutionary Biology at Princeton University. He then returned to Colombia to take a position as an Assistant Professor at the Department of Biology at Pontificia Universidad Javeriana. During his tenure there, he created the Laboratory of Population Ecology and worked on the reproductive ecology of cloud forest birds and the effects of forest fragmentation on these communities and became chair of the Department of Biology. Jorge returned to the US to expand his academic opportunities working with Steve Hubbell on models of tropical forest dynamics. He then was hired by the University of Hawaii to model the dynamics of bird diseases in Hawaii as part of a Biocomplexity project looking at the impact of malaria and pox on Hawaiian native birds. Dr. Ahumada is broadly interested in applying mathematical models to solve applied conservation problems. He has worked on the impacts of climate change on disease and biodiversity, incorporating the effects of temperature and rainfall on models of disease-transmitting vectors and more recently on the use of camera traps for monitoring vertebrates.
