Allison Ray, Ph.D.

Research Excellence Lead for Science & Technology

Research Areas:


Allison Ray is the Research Excellence Lead for Science & Technology. In this role, she assists Dr. Marianne Walck, Deputy Laboratory Director for Science and Technology and Chief Research Officer, with various laboratory and corporate initiatives for improving research outcomes, and in executing strategy to continuously improve the quality, impact and relevance of INL research. Allison comes from the Chemistry and Radiation Measurement Department, where she works on programs funded through DOE EERE’s Bioenergy Technologies Office (BETO). Allison has expertise in biomass science and feedstock logistics, focusing on feedstock cost reduction, and understanding and managing feedstock variability and quality for effective biochemical and thermochemical conversion into fuels and chemicals. Currently, she leads the Feedstock Variability Task as part of BETO’s Feedstock Conversion Interface Consortium (FCIC), representing a multi-disciplinary team of scientists and engineers across six national laboratories, including INL, NREL, LBNL, LANL, ORNL, and SNL. Allison graduated with a Ph.D. in environmental microbiology from Idaho State University. Her dissertation focused on microbially-mediated metals reduction for bioremediation of metals and radionuclides in subsurface environments. She also earned her MS and BS in Agricultural & Biological Engineering from Purdue University.
