Timothy Rebbeck

Timothy Rebbeck is Professor of Epidemiology in the Department of Biostatistics, Epidemiology, and Informatics at the Perelman School of Medicine, University of Pennsylvania. His research integrates cancer genetics with population health, focusing on genetic susceptibility and disparities in cancer outcomes across diverse populations, particularly African ancestry groups.

His work centers on identifying cancer genes and characterizing their relationship with cancer occurrence and outcomes within demographic, biochemical, environmental, and physiological contexts. Key research areas include prostate, breast, and endometrial cancers, with emphasis on genetic epidemiology, tumor biomarkers, and the impact of structural determinants of health. Recent studies investigate neighborhood effects on telomere length, genetic risk prediction in prostate cancer, and community engagement in genomic research.

Analysis of his 2022-2025 publications reveals leadership in large-scale genomic studies addressing racial disparities in prostate cancer diagnostics and treatment. His work spans Veterans Health Administration cohorts, international collaborations in Sub-Saharan Africa, and methodological advances in genetic risk modeling. A consistent theme is optimizing cancer screening protocols for high-risk populations while addressing barriers to care in underserved communities.
