Dr. Yang’s research interests are water resources management, water-energy-food nexus, agent-based modeling, coupled natural and human complex systems, climate change risk assessment, international rivers, transboundary water policy, hydro-ecology and urban stormwater management. Dr. Yang has extensive experiences in water management in the Great Himalayan, Sub-Saharan Africa region and the Western US. He leads more than 12 research projects (more than $3 million) funded by the U.S. Department of Energy, National Science Foundation, the Work Bank, the International Food Policy Research Institute, the Consultative Group on International Agricultural Research and the Research Triangle Institute. Most of these projects evaluated climate change risk and social development influence on the water-energy-food-environment nexus for large river basins such as the Colorado, Columbia, Brahmaputra, Indus, Ayeyarwady, Mekong, Amu Darya, Yellow and Niger. Along with the system modeling skill, Dr. Yang’s research can answer difficult questions of uncertain climate change impact and anthropogenic influence on water-energy-food-environment nexus quantitatively.
Prior to joining Lehigh’s faculty, Dr. Yang was a research assistant professor in the University of Massachusetts, Amherst. He is an author and co-author of 50 peer-reviewed journal papers and 50 conference papers. Dr. Yang received the NSF CAREER Award in 2020. Dr. Yang is a regular reviewer for top-ranking journals in the water resources management and he serves as an Associate Editor for the Journal of Water Resources Planning and Management – ASCE. He was also the Chair of the Water and Society Task Committee in the American Geographical Union from 2017 to 2019.
Teaching and Service
Dr. Yang is teaching Fluid Mechanics (CEE122), Water Resources Engineering I (CEE222). Engineering Hydrology (CEE320) and GIS for Civil and Environmental Engineering (CEE326) in the CEE Department. He is a member of undergraduate curriculum committee and website committee.
