Dr. Yonas Demissie is an Associate Professor of Civil and Environmental Engineering at Washington State University (WSU). He has more than 15 years of experience in hydroclimatology, studying the causes and consequences of hydrological extremes such as floods and droughts. His current research focuses on improving the characterization and prediction of hydrological extremes and associated risks, updating engineering standards and designs to ensure sustainable and resilient infrastructure and water management programs. He also has experience in watershed hydrology and water quality research. He served as a principal investigator on multiple research projects focused on climate change and its link to floods and droughts. He has authored several articles and book chapters on the topics.
Prior to joining WSU, he was a postdoctoral research associate in the Environmental Science Division at Argonne National Laboratory. He received a bachelor’s degree in agricultural engineering from Haramaya University in Ethiopia, a master’s degree in water resources engineering and hydrology from Vrije Universiteit Brussel in Belgium, and a doctoral degree in civil engineering from the University of Illinois at Urbana-Champaign.
