Dr. Marc S. Mendonca is a Professor of Radiation Oncology & Medical and Molecular Genetics, and Director of Radiation and Cancer Biology at Indiana University School of Medicine. Dr. Mendonca is an internationally known researcher with extensive expertise in X-ray and proton radiation biology related to the clinical uses of radiation. Dr. Mendonca’s research investigations are focused on gaining a better understanding of radiation’s ability to both heal and harm. His research can be generally separated into two main areas: 1) Understanding the mechanism of radiation-induced cancer and its prevention by natural antioxidants, and 2) Increasing the effectiveness of radiation as a treatment for lung and pancreatic cancers by biological (alteration of NF-kB activity and Warburg metabolism) and physical approaches (protons and nanoparticles) to improve tumor control and minimize damage to normal tissues. Since 2011 Dr. Mendonca has also served as the Editor-in-Chief of the journal Radiation Research.
