Pierre Montay-Gruel graduated in 2014 from the Ecole Normale Supérieure and Université Paris-Saclay in radiobiology. After a PhD and post-doc on the topic of FLASH radiotherapy, he joined the University of California as a post-doctoral fellow, working on new techniques to prevent radiation-induced normal tissue injury. In 2021, he joined Iridium Netwerk (Antwerp, Belgium) as a radiobiologist. In 2022, he participated in the creation of the Antwerp Research in Radiation Oncology (AReRO) group at the Centre for Oncological Research (CORE) of the University of Antwerp, where he leads the radiobiology group. His research focuses on preclinical studies to increase the therapeutic window of radiation therapy, especially in the context of breast cancer treatment, including FLASH radiotherapy, cellular and molecular interventions.
