Jennifer Bobb, PhD, aims to apply rigorous statistical methods to address important problems in public health. She is interested in statistical issues that occur when data that were not originally collected for research purposes, such as administrative claims data or electronic health records, are used for addressing scientific questions relevant to clinical practice and health policy.
At Kaiser Permanente Washington Health Research Institute (KPWHRI), Dr. Bobb collaborates with scientists across a broad range of research areas, including mental and behavioral health and social determinants of health. As an investigator with the Health Care Systems Addictions Research Network, she provides statistical leadership on pragmatic clinical trials at Kaiser Permanente Washington and other health systems. She is the lead statistician on a stepped wedge trial evaluating how mental health and wellness integration at Kaiser Permanente Washington affects clinical care and health outcomes, as well as a multi-site pragmatic trial to evaluate a program for increasing medication treatment for opioid use disorders within primary care settings. She has developed statistical guidance to address methodological challenges introduced by pragmatic trials that leverage electronic health records data to define study eligibility and outcomes.
With expertise in environmental biostatistics, Dr. Bobb has led large-scale epidemiological investigations on the health effects of exposure to extreme heat and air pollution. She developed flexible modeling approaches for estimating the health effects of multi-pollutant mixtures that broadly apply to settings where large numbers of exposures may interact or have complex relationships with health, along with publicly available software implementing these methods. In recent work, she is collaborating on the Moving to Health study, which explores whether changes in the built environment, such as access to healthy foods and walkability, affect long-term weight and diabetes management.
Dr. Bobb is an affiliate assistant professor in biostatistics at the University of Washington and an associate editor of the journal Biostatistics. She serves on the Committee for Funded Research of the American Statistical Association and is a member of the International Biometric Society. Before joining KPWHRI, Dr. Bobb completed her PhD in biostatistics at the Johns Hopkins Bloomberg School of Public Health in 2012, followed by a postdoctoral fellowship at the Harvard T.H. Chan School of Public Health.
