About me

Jamie O. Lo, M.D., M.C.R. is an Associate Professor in the Department of Ob/Gyn and Department of Urology at OHSU, a Core Scientist at the Oregon National Primate Research Center (ONPRC), and adjunct faculty at the University of Georgia. Dr. Lo received a B.A. in Molecular Cell Biology (Immunology) and Asian American Studies from the University of California, Berkeley, and an MD and MCR from OHSU. She completed her residency training in obstetrics and gynecology at the University of Utah and her subspecialty training in Maternal-Fetal Medicine at OHSU.


As a clinician-scientist with more than 15 years of experience, her efforts encompass clinical care, education, and clinical and translational research. She is the Co-Director of PMedIC (Pacific Northwest Biomedical Innovation Co-Laboratory), a joint research collaboration between OHSU and the US Department of Energy’s Pacific Northwest National Laboratory. Dr. Lo is also the Recruitment Director for OHSU’s NIH/NICHD Women’s Reproductive Health Research (WRHR) K12 Program, the Chair of the Society for Reproductive Investigation Grants Committee, and serves on the Obstetrics Council for the Perinatal Research Society. Her passion for education has been recognized by numerous teaching awards and has been demonstrated through her role as the Assistant OB/Gyn Residency Program Director - Research and Scholarship, and as a member of the OHSU MD/PhD Committee and Society for Maternal-Fetal Medicine Education Committee overseeing the Fellows Lecture Series.


Dr. Lo’s career has been focused on the effects of environmental exposures, especially substance use, on reproductive health and offspring outcomes. Specifically, she is studying the underlying mechanisms between paternal and maternal environmental factors, and placental perfusion and offspring development. Her laboratory is currently investigating the impact of paternal and maternal use of cannabis prior to conception, during pregnancy, and in the postnatal period on reproductive health and offspring outcomes. In addition, her laboratory is also actively studying early brain and child development outcomes following maternal high-risk exposures, including substance use, and the mechanistic gaps between maternal substance use and known adverse child outcomes as part of the multi-center NIH/NIDA/NICHD HEALthy Brain and Child Development study (HBCD).


She is a well-regarded national speaker on the effects of cannabis use on reproductive health and pregnancy, and serves on the editorial board of several peer-reviewed journals. Dr. Lo’s research has been both federally and non-federally funded by grants from the NIH/NICHD, NIH/NIDA, Silver Family Foundation, March of Dimes, American Society for Reproductive Medicine, Society for Maternal-Fetal Medicine, and Medical Research Foundation of Oregon.
