Research and Teaching Interests
Dr. Lei’s work is in the BSysE (Bioenergy and Bioproducts Engineering), research emphasis area at the Bioproducts, Sciences and Engineering Laboratory (BSEL) on the WSU Tri-Cities campus. His focus is on discovering and applying novel approaches for renewable energy and value added process development of agricultural feedstocks and products. Dr. Lei is working on a number of exciting research projects which involve design and development of processing technology, optimization of processes, reaction kinetics, process modeling, and value added product development.
Dr. Hanwu Lei is an assistant professor and graduate faculty at Department of Biological Systems Engineering and BSEL at Washington State University. He received his Ph.D. in Biosystems and Agricultural Engineering from University of Minnesota at Twin-Cities in 2006, his M.S. in Biosystems and Agricultural Engineering from University of Minnesota in 2003, and his B.S. in Grain Engineering from Wuxi University of Light Industry in China in 1992. Prior to his arrival at WSU, Dr. Lei was an assistant professor and bioprocess engineer and graduate faculty of Agricultural and Biosystems Engineering at South Dakota State University (SDSU), and before joining the faculty at SDSU in 2007, he worked at University of Minnesota as a research associate and process engineer in 2006-2007.
Dr. Lei has worked for more than ten years in novel approaches for renewable energy and value added process development for agricultural feedstocks and products. Dr. Lei’s research interests include biomass thermochemical conversions (torrefaction, pyrolysis, liquefaction, aqueous phase reforming, catalytic processes, and bio-oil upgrading) to produce aromatics, hydrocarbons, hydrogen, syngas, biofuels, bioproducts, and use of biochar as a form of carbon sequestration on the impact of fuels process and environment. Dr. Lei’s research activities also include biomass pretreatment for biological or chemical conversion to renewable energy and bioproducts, especially working on hydrothermal pretreatment and clean fractionation processes.
Dr. Lei is the author and co-author of over 100 peer reviewed journal articles and papers at national and international conferences. He has 11 US patent applications and invention disclosures. Dr. Lei is the USDA and DOE grant proposal programs reviewer/panelist, a division editor of Renewable Energy System and an associate editor of Agro-Product and Food Processing Engineering, and is serving on the editorial board for the International Journal of Agricultural and Biological Engineering. He is also an Editorial Board Member for the Journal of Sustainable Bioenergy Systems and serving as a technical reviewer for more than 30 peer-reviewed journals.
