Jeffrey Lacey, Ph.D. Staff Scientist Research Areas:
Conversion Interface; Advanced Preprocessing Biography:
Dr. Jeff Lacey is a research scientist at the Idaho National Laboratory in the Biological Processing Department. His experience includes bioenergy research, gene expression profiling, and environmental remediation. His interests lie in feedstock valorization by characterizing the complexity of biomass and municipal solid waste (MSW) and using this information to improve the economics and performance of these feedstocks in conversion processes. His current work has focused on the development of deployable waste processing systems to produce clean, sorted, and uniform feedstocks from MSW. He is also working on biomass feedstock quality improvement through the deconstruction and separation of biomass into fractions with unique physical and chemical properties. He holds a Ph.D. in plant science from the University of Idaho (2009), a M.S. in Waste Management and Environmental Science from Idaho State University (1999), and a B.S. in Zoology from Idaho State University (1996). He has been inducted into the INL Inventor's Hall of Fame three times, in 2014, 2015, and 2017. He is an author on over 20 peer reviewed publications and is an inventor on over 40 US and international patents. He is also the co-owner of JEM Innovations, a small start-up business that specializes in additive manufacturing techniques and robotics (3D printing, laser cutting) to develop products for hunting and outdoor sports, automotive restoration, and other prototyping.
