Missions
The activities of the PHABIO group focus on developing models and acquiring biological data in order to predict the effects of ionizing radiation on living matter and to contribute to the development of innovative radiotherapies. These developments are carried out within a multi-scale approach that includes cross-section calculations, the development of Monte Carlo codes, and the advancement of the NanOx model for biological dose prediction.
As part of a collaboration with the University of Rosario (Argentina), the PHABIO group at IP2I is recruiting a postdoctoral researcher to contribute to the development of Geant4-DNA (an open-source Monte Carlo code for the transport of low-energy particles) and to the NanOx model for biological dose prediction developed at IP2I.
Activities
As part of your mission, you will:
• Develop the low-energy Monte Carlo code (Geant4-DNA) by transferring cross sections from the LQD code to Geant4-DNA.
• Contribute to the development of the NanOx biological dose prediction model, in particular by studying the influence of different parameters (e.g., interaction cross sections, cell geometry, etc.) on cell survival rates.
Skills
We are looking for a specialist in radiation–matter interactions with proven experience in Monte Carlo simulations and programming in C++ and Python. The candidate will work within a dynamic international collaboration, offering a stimulating and multidisciplinary research environment.
Work Context
The Institute of Physics of the Two Infinities (IP2I, ip2i.in2p3.fr) is a joint research unit of CNRS and Claude Bernard University Lyon 1 (UCBL). IP2I is involved in most areas of subatomic physics and also has strong expertise in astroparticles and cosmology. The laboratory also conducts interdisciplinary research related to the environment, health, and nuclear energy. It is composed of about 250 people, including 42 faculty members, 32 permanent researchers, 94 engineers and technicians, and more than 60 PhD students and postdocs.
In addition, this postdoctoral position is part of the European project MAMBA, which also provides funding for travel between France and Argentina.
