He is a member of the IUCN Species Survival Commission, a senior Wildlife Ecologist at the US National Park Service, and Affiliate Faculty at Colorado State University. His work is on the front lines of applied conservation science in Africa and North America. From an academic perspective, Dr. Ransom's research focuses on restoration science, phenology of biological phenomena, behavioural adaptation to environmental change, and the importance of protected areas to landscape level conservation.
