Biography

Shonnard earned a Ph.D. from the University of California at Davis and had appointments at Lawrence Livermore National Laboratory and the University of California at Berkeley prior to joining Michigan Technological University in 1993.[4] He has served on advisory committees for the DOE, UDSA, and the REMADE Institute in areas of biomass research and development and materials circular economy. He is co-author of two green engineering and sustainable engineering textbooks[5][6] and has published over 200 works appearing in peer-reviewed research journals, technical reports, and conference proceedings.[7]

Research interests

Shonnard has broad research interests that include diffusion and adsorption of pollutants in soils, atmospheric transport of hazardous compounds, environmental risk assessment, in-situ subsurface remediation, environmentally-conscious design of chemical processes, advanced biofuels reaction engineering, and applications of pyrolysis to waste plastics recycling. Sponsors of his research program include federal (NSF, DOE, DARPA, USDA, FAA), state (MI MTRAC), and numerous industrial firms. He holds patents in enzymatic and chemical conversion technologies and is founder of a company, SuPyRec, to commercialize chemical recycling of waste plastics.
