Research Interests
Dr. Sumit Subudhi is a medical oncologist and immunologist whose research focuses on the mechanisms and pathways within the immune system that are responsible for tumor rejection and clinical benefit. Dr. Subudhi’s medical training began when he enrolled in the MD/PhD program at The University of Chicago Pritzker School of Medicine in 1998. Dr. Subudhi’s predoctoral studies included examining the role of B7-H1 (PD-L1), an immune checkpoint, in regulating T cell–mediated immune responses. He completed his PhD in 2004, his MD in 2007, his internal medicine residency at the New York-Presbyterian Hospital/Weill Cornell Medical Center in 2009, and his medical oncology fellowship at Memorial Sloan Kettering Cancer Center (MSKCC) in 2013. During his medical training, Dr. Subudhi became interested in the field of tumor immunology and subsequently completed a postdoctoral fellowship in Dr. James P. Allison’s laboratory at MSKCC. In Dr. Allison’s laboratory (now at MD Anderson), Dr. Subudhi began to examine the effects of targeting immune checkpoints (e.g., CTLA-4 and PD-1) in prostate cancer and continues to uncover the mechanisms that tumors use to evade the immune system.
A fter completing his fellowship at MSKCC, Dr. Subudhi was appointed as an Advanced Scholar Instructor at MD Anderson Cancer Center in 2013, and more recently (2014) as an Assistant Professor in Genitourinary Medical Oncology. His focus is on investigating optimal combinations of immune checkpoint blockade-based therapies and on developing immunological biomarkers to predict treatment responses, with the hope of ultimately producing durable and even curative responses in patients with prostate cancer. Dr. Subudhi was awarded the Prostate Cancer Foundation Young Investigator Award in 2014 to pursue these studies. Dr. Subudhi has also been investigating the immunological differences between primary prostate cancer and the bone metastasis microenvironment.
