Portland State University's Biology Department includes over 21 faculty, 1,200 undergraduate majors, and over 65 graduate students and post-docs. Our faculty take an integrative approach to biology, encompassing all levels of biological organization from molecules to ecosystems.

Our offices and laboratories are housed at the PSU main campus, in the Science Research & Teaching Center (SRTC) and Science Building 1 (SB1), alongside the Environmental Science, Chemistry, and Physics departments. The Biology department also has research, teaching, and office spaces at the Robertson Collaborative Life Sciences Building (RLSB) on the Willamette River waterfront, alongside Oregon Health & Science University (OHSU) research and medical and dental school spaces, as well as the Oregon State University school of pharmacy.

The close proximity of the Biology department with other PSU departments, as well as OHSU and OSU spaces, helps to foster interdisciplinary research and other connections among our departments and institutions. Teaching and research laboratories are further supported by the Herbarium, Invertebrate and Vertebrate Museums, extremophile DNA and microbial culture collections, an aquatic organism rearing facility, greenhouses and an electron microscope facility.

Recent Publications from the Biology Department

Robyn Dove, a doctoral student in the Ballhorn chemical ecology lab, published a first-author paper in the Journal of Northwest Science! The paper, titled “Ecoregion—rather than sympatric legumes—influences symbiotic Bradyrhizobium associations in invasive Scotch Broom (Cytisus scoparius) in the Pacific Northwest,” reports on her findings from a field study that covered a large geographic range in the Pacific Northwest.

Dr. Anna-Louise Reysenbach has also recently published a paper in Proceedings of the National Academy of Sciences titled "Complex subsurface hydrothermal fluid mixing at a submarine arc volcano supports distinct and highly diverse microbial communities."
