Bettye L. (Smith) Maddux received her Ph.D. from the University of Texas at Austin 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 also joined Oregon State University as the Managing Director for the Center for Sustainable Materials Chemistry (CSMC). Previously, she served as a 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 is actively involved in policy issues relating to Environmental, Health and Safety needs for engineered nanoscale materials. She serves on the Advisory board of the Nanosafety Consortium for Carbon. She also serves as 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.

Current Research Interests

NanoEHS, nanomaterial-biological interactions, nanoparticle-cell interactions and intracellular fate, biomaterials, and sustainable chemistry
