Cohorts

Dr. Denham has examined the use of the emergency department as a safety net in Medicaid, the impact of the ACA Medicaid expansions on coverage, and trends and factors in drug overdose mortality. She is particularly interested in how Medicaid managed care may advance health equity or exacerbate existing disparities in health outcomes and patient experiences. Dr. Denham's methodological work has addressed data quality and measurement issues in large administrative datasets.

Dr. Chen is a clinical neuropsychologist whose research centers on digital health and wearable sensor technologies for assessing neurological and cognitive symptoms, including fatigue, post-COVID conditions, and early markers of cognitive decline. Her work emphasizes remote, scalable assessment tools with a focus on improving representation and access in neurological research, particularly in aging and Alzheimer's disease studies.

Dr. Senteio's work uses health informatics and mixed methods to study how information and technology shape health outcomes and inequities — especially among racial and underserved populations. His research includes studies on racial inequities in chronic disease care, access to health information, and community-based health communication interventions.
