Dr.  Haiman is Co-Leader of the Cancer Epidemiology Research Program at USC Norris, a professor of preventive medicine at the Keck School of Medicine of USC, and AFLAC Chair in Cancer Research. He also leads  the Epidemiology and Genetics division in the Department of Preventive Medicine. Dr. Haiman is a genetic epidemiologist whose research is focused on exploring racial and ethnic disparities in cancer risk, with the goal of developing approaches to reduce these disparities. He is co-principal investigator of the Multiethnic Cohort (MEC), a large prospective study of cancer in primarily non-European ancestry populations that has been the foundation of his scientific investigation into the genetic risk of cancer, initially through genome-wide association studies (GWAS) and more recently in large-scale genomic consortia in minority populations that employ next-generation sequencing technology. In addition to these leadership and administrative research positions, he has vast experience in directing large consortia and is currently the scientific leader of the African Ancestry Prostate Cancer Consortium (AAPC).
