Dr. Diptasri M. Mandal is a Professor in the Department of Genetics at Louisiana State University Health Sciences Center. She received her PhD. in Human Genetics from the Department of Biometry and Genetics at LSU Health Sciences Center in 1996. She joined the Department of Medicine in 1997, and in June 2000 moved to the Department of Genetics. She ascended through the academic ranks and was promoted to Professor in 2015.

The major focus of her research is genetic studies of complex human traits and diseases, especially cancer. Studies are underway to identify disease susceptible loci for hereditary prostate cancer and lung cancer using linkage, association, and next generation sequencing analyes. She is an invited member of International Consortium of Prostate Cancer Genetics (ICPCG), UK PRACTICAL Consortium, and Genetic Epidemiology of Lung Cancer Consortium (GELCC).
