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 and Chemical Processing Department. His experience includes bioenergy research, gene expression profiling, and environmental remediation. His interests lie in feedstock valorization by characterizing the natural complexity of biomass feedstocks and using this information to improve the economics and performance of biomass feedstocks in conversion processes. His current work has focused on biomass feedstock quality improvement through the deconstruction and separation of biomass into fractions with unique physical and chemical properties. He also participates in the Renewable Carbon Fiber Consortium, a group of researchers led by National Renewable Energy Laboratory scientists working to produce acrylonitrile-based carbon fibers from biomass feedstocks. He is a member of the Scientific Advisory Board for this consortium. He holds a Ph.D. in plant science from the University of Idaho (2009). He has been named to the INL Inventors Hall of Fame twice, in 2014 and 2015. 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, medical devices, and other prototyping.
