Bettye L.S. Maddux

Bettye L. (Smith) Maddux received her Ph.D. from the University of Texas at Austin (with a joint appointment at M.D. Anderson Cancer Center, Science Park Research Division) studying the effects of the potent carcinogen, benzo[a]pyrene diol epoxide on nucleosomal DNA at single nucleotide resolution. She joined the University of Oregon and the Oregon Nanoscience and Microtechnologies Institute (ONAMI) as assistant director of SNNI in February 2006. In 2011, she joined Oregon State University as the Managing Director for the Center for Sustainable Materials Chemistry (CSMC), an NSF-funded Center for Chemical Innovation. She is also the Research Program Administrator for the College of Science at Oregon State University and honorary member of the Bill Casey group at UC Davis

Previously, she served as an associate specialist and research biophysicist at the University of California, Santa Barbara with joint appointments in the Materials Research Laboratory, the Department of Physics, and the Marine Biotechnology Institute. Her major research interests included studying the mechanisms controlling the biosynthesis and self assembly of biocomposite materials (e.g. coccolithophores, abalone shells, diatoms) and analyzing the nanoscale properties of strong and tough biopolymers.

She participated on policy issues relating to Environmental, Health and Safety needs for engineered nanoscale materials through standards and other organizations. She served on the Advisory board of the Nanosafety Consortium for Carbon and the Nanomaterials-Biological Interactions Knowledgebase. She is an ad hoc reviewer for the American Chemical Society.  She has published peer-reviewed research articles, a book chapter, policy-related reports and invited articles as 'Bettye L. Smith’ and more recently as ‘Bettye L.S. Maddux’ in the fields of nanotechnology, biophysics, biochemistry, materials science, and chemical carcinogenesis. Her current research project examines ways to harness the biosynthetic capacities of algae to make unique and valuable coproducts. (NSF EFRI #1240488)
