Brad Wahlen, Ph.D.

Research Scientist

Research Areas:
Biofuels Characterization

Biography:
Dr. Bradley D. Wahlen is a research scientist in the department of Biological and Chemical Processing at Idaho National Laboratory with a background in microbial metabolism and enzymology. As a doctoral student at Utah State University, he worked on projects related to the production and characterization of biofuels from microbes (algae, yeast and bacteria) and continues to have a strong interest in the biological production of chemicals and fuel. Currently (2016), he is working on storage technologies to overcome logistical challenges to microalgae biofuel production and approaches to develop co-products that could make algae biofuel economically sustainable. He comes to INL from the mineral processing industry where he worked as a research chemist to develop biological and chemical processes to overcome challenges to gold, copper, and titanium production. He received his doctorate in biochemistry from Utah State University and his bachelor’s from Idaho State University, where he was honored as the Thomas F. Emery Research Scholar-Outstanding Graduate Student in Biochemistry, Department of Chemistry and Biochemistry (USU) and the Department of Biological Sciences’ Outstanding Graduating Student in 2006 (ISU).
