Dr. Ryan J. Longman joined the East-West Center’s Research Program as a Fellow in November 2019 and has just recently joined the Pacific Islands Development Program. Prior working at the EWC, he completed his Ph.D. and M.A. degrees in Geography at the University of Hawai‘i at Mānoa (UHM). Since graduation, he has worked as a Lecturer within the UH system, where he has taught classes on climate, water resources, and the natural environment. He has also worked as research scientist on a wide range of projects related to climate science including the development of rainfall and temperature maps for Hawai‘i. Dr. Longman serves as affiliate faculty member for the Water Resources Research Center at UHM. Between October 2018 and September 2019, Dr. Longman assisted in the development and delivery of a specialized project-preparation training course on climate change adaptation and climate finance that has been conducted in 10-Pacific Island Nations. He continues to work on projects that focus on building resilience and adapting to climate change in the Pacific.
