Britta Torgrimson-Ojerio, PhD, RN, is a nurse researcher and Director of the Clinical Research and Trials Unit at CHR. She has research expertise in clinical trials, human physiology, women’s health, and preventative medicine, and is a certified nurse with experience in direct nursing clinical care. Much of her current research focuses on public health and the health care delivery system.

Dr. Torgrimson-Ojerio directs CHR-based vaccine trials, oncology trials, cardiovascular trials, and a variety of other specialty clinical trials. She is a Sub-Investigator on the COVID-19 portfolio of clinical trials at CHR and serves as a site principal investigator and co-investigator on health care delivery system and public health studies, including research on tear gas.

Dr. Torgrimson-Ojerio received her PhD in human physiology from the University of Oregon in 2007. She then pursued postdoctoral research at Oregon Health & Science University School of Nursing, where her training included clinical trials, nursing research, and RN licensure as a Jonas Scholar in the accelerated nursing program. After working as a nurse in a pediatric ER, she joined CHR in 2015 as a clinical research specialist and nurse case manager. She was appointed Research Clinic Coordinator in 2016, Senior Manager of Clinical Research Support Services in 2019, and Director of the Clinical Research and Trials Unit and Director of the Learning Health System at CHR in 2021.

Dr. Torgrimson-Ojerio is a member of the Kaiser Permanente National Council of Clinical Trials, the CHR Leadership Team, the KPNW Operational Interface Council, the CHR Advisory Biospecimen Committee, the Kaiser Permanente Clinical Trials Finance Optimization Group, Kaiser Permanente Clinical Trials Digital Ecosystem Initiative, and the Kaiser Permanente National Nursing Evidence Based Practice and Research Council.
