Georgiana Purdy, Ph.D. - Program Director

Dr. Purdy earned her bachelor’s degrees in Microbiology and Cell Science (B.S., with honors) and History (B.A., with honors) from the University of Florida in 1998. She subsequently obtained her Ph.D. from the University of Texas at Austin in 2003. Dr. Purdy joined the OHSU MMI Department in 2008 as an Assistant Professor and established her independent research program focused on M. tuberculosis. The goals of the Purdy Lab are to further define the intrinsic resistance of the pathogen to the host immune response and antibiotics, delineate pathways in mycobacterial cell wall biogenesis, and identify targets and new strategies for future drug therapy. The lab combines the approaches of bacterial genetics, biochemistry and cell biology to achieve these goals. Dr. Purdy became an Associate Professor in 2014 and received tenure in 2016. Work in the Purdy lab is funded by the NIH. Dr. Purdy has significantly contributed to the education and mentoring of graduate students at OHSU. She has been course director of the CONJ660 Research Rotation Talks course and the MBIM615 Host-Pathogen Interactions course. She has served as a Graduate Program Director since 2016.

Alex Nechiporuk, Ph.D. - Assistant Director, Curriculum 

Dr. Nechiporuk received his doctorate in Human Genetics from University of Utah in 2002. He did his postdoctoral training in developmental biology at University of Washington. Dr. Nechiporuk joined the faculty at OHSU in 2008. Dr. Nechiporuk is currently an associate professor of Cell, Developmental & Cancer Biology in the OHSU School of Medicine, and a member of the OHSU Knight Cancer Institute. The Nechiporuk laboratory studies development of the peripheral nervous system using zebrafish as a model. They focus on roles of collective cell migration and axonal transport during embryonic development.
