Dr. Limoli is a Professor of Radiation Oncology at the University of California Irvine (UCI). He holds a BS degree in chemistry from MIT and a PhD in biomedical sciences from UCSD. Over the years he has served on and chaired numerous peer-review committees and has been the recipient of multiple extramural grants from agencies such as the NINDS, NCI, NASA, ACS and DTRA. He served as the 65th president of the Radiation Research Society and is an internationally recognized expert in radiation biology with over 175 publications in peer reviewed journals and book chapters. He is considered one of the world’s leading experts on the use of FLASH radiotherapy. His research has focused on radiation effects in the CNS, where he has defined many of the mechanisms that contribute to radiation-induced cognitive dysfunction. His work has since defined the importance of oxidative stress in the brain, how irradiation disrupts neuronal structure and synaptic integrity and how stem cells can be used to offset the adverse effects of both radio- and chemotherapy in the brain.
