Professor Chandan Guha obtained his MBBS from the University of Calcutta, India and his PhD in Immunology at Medical University of South Carolina, Charleston. He completed his residency training in Radiation Oncology at Washington University and the Albert Einstein College of Medicine, Bronx, NY. He is the founding Director of the Institute for Onco-Physics and Professor of Radiation Oncology, Urology and Pathology, Vice Chairman, and the Director of Translational Research of the Department of Radiation Oncology at Montefiore Medical Center, Albert Einstein College of Medicine, New York. His laboratory is investigating several approaches to combine immunotherapy with radiation therapy and has proposed that hypofractionated radiation of tumors could produce autologous in situ tumor vaccines. Besides immunotherapy, his laboratory is developing strategies for stem cell-based therapies to mitigate and treat radiation injury and to induce regeneration of irradiated organs, such as, liver, intestine and lung. His group discovered that hepatic irradiation could be used as a preparative regimen for liver cell transplantation to promote repopulation of stem cells and adult hepatocytes in host liver. Dr. Guha is funded by multiple grants from the National Institute of Health and has collaborations with several Industrial partners to develop novel applications of radiation and ultrasound for tumor immunotherapy and regenerative medicine.
