Lynn Wendt, Ph.D.

Research Scientist

Research Areas:
​Advanced Preprocessing


Lynn Wendt has been a staff scientist at the Idaho National Laboratory since 2002. She holds a bachelor’s degree in biochemistry from the University of Minnesota, a master's in biology from Idaho State University, and a Ph.D in environmental science from the University of Idaho.​ Lynn has worked on feedstock supply issues for eight years, on topics related to preservation of biomass during storage. The main emphasis of this research has been on preserving both dry matter and quality of stored biomass, as well as identifying the logistics operations and associated costs of bulk, high moisture biomass and large-scale storage at a biorefinery gate. Lynn is also investigating algal biomass stabilization and preprocessing approaches to reduce the risk of feedstock loss associated with seasonal variability of algal biomass.
