Beth Hofstad has over 10 years of research experience. Subject areas include bioremediation, pharmaceuticals, enzyme, organic acid and ethanol production. She currently works in Chemical and Biological Process Development group. Within this group, she is focused on creating biofuels and bioproducts using fungal strains. She is currently working with fellow scientists identifying and quantifying cellulose degrading enzymes using activity based chemical probes. She is assisting in research using proteomics to identify proteins involved in the production of lipids in algae.

She has been part of many publications, including journal articles, conference proceedings and technical reports. Mrs. Hofstad originally joined PNNL in 1990 and rejoined PNNL in 1997 after college.
