Bobb applies 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.
As an investigator with the Health Care Systems Addictions Research Network, she provides statistical leadership on pragmatic clinical trials at a range of health systems. Bobb is the lead statistician on a stepped wedge trial evaluating how mental health and wellness integration affects clinical care and health outcomes.
With expertise in environmental biostatistics, 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.
