Dr. Laurence Lebaron-Jacobs has been working at the French Atomic Energy Commission (CEA) since 2002.

She studied external dosimetry and radiobiology at the Paris XI University, where she obtained her PhD degree in radiobiology - radiopathology in 1994. She received an MD degree from Pierre et Marie Curie University in 1996.

During her PhD at the Institute of Protection and Nuclear Safety (IPSN), she was involved in a project of real-time external dosimetry aboard the MIR Russian orbital station. From 1995 to 2001, she worked at the IPSN in the areas of medical management of irradiated victims and research related to effects of ionizing radiation (gamma, heavy ions) on the central nervous system.

Dr. Lebaron-Jacobs is currently physician - international advisor in radiobiology, radiopathology and nuclear toxicology to the CEA in the Directorate of Fundamental Research (DRF) within the Institute of Biology François Jacob (IBFJ), unit of Health Protection against Ionising Radiation and Nuclear Toxics (CEA/Cadarache).

She has been senior lecturer since 2022 for her teaching activities in radiobiology, radiopathology and radiotoxicology.

She has been the vice-chair of the French Compensation Committee for Victims of Nuclear Testing since 2024.

She has been involved in European research projects (H2020, Horizon) dedicated to develop new mitigation strategies for tritium releases and to work towards a better understanding of the health and environmental impacts of tritium.
