Department: Civil and Environmental Engineering

Position: Assistant Professor

Address: STEPS Building 466
1 West Packer Avenue
Bethlehem, PA 18015

Areas of Research

  • Water Resources
  • Water-Energy-Food Nexus
  • Agent-based Modeling
  • Systems Analysis


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 geographic information science. Dr. Yang has extensive experiences in water management in the Great Himalayan and Sub-Saharan Africa region. He leads more than 10 research projects (totaling more than $2.5 million) funded by the U.S. Department of Energy, 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 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 more than 27 peer-reviewed journal papers and 35 conference papers. Dr. Yang is a regular reviewer for top-ranking journals in the water resources management and he serves as an Associate Editor for Journal of Water Resources Planning and Management – ASCE. He is also the Deputy Chair of Water and Society Task Committee in the American Geographical Union.

Dr. Yang is teaching Mechanics of Fluid in the Department of Civil and Environmental Engineering and his is currently developing a course of GIS for Civil Engineer for graduate students and seniors.
