Speakers: Associate Professor Guatelli (University of Wollongong) & Prof Sebastien Incerti (University of Bordeaux)

Associate Professor Susanna Guatelli, Centre For Medical and Radiation Physics, University of Wollongong, Australia, is an international leading expert of the Geant4 Monte Carlo code for medical physics applications, working in the field since 2002.
Since 2018, S. Guatelli is member of the Steering Board of the Geant4 International Collaboration in her role of Coordinator of the Geant4 Advanced Examples Working Group. Since 2018, she leads the Geant4 Medical Simulation Benchmarking Group dedicated to the systematic testing of Geant4 for medical applications. S. Guatelli has extensive expertise in teaching Geant4 at various levels and organised many Geant4 short courses addressed to the use of this Monte Carlo code in medical physics.
S. Guatelli has been chair/co-chair of several international workshops and conference sessions dedicated to Monte Carlo codes applied to medical physics. She is Associate Editor of Physica Medica and of Applied Radiation and Isotopes.
In 2021, she was awarded with the prestigious Women in Physics Lecturer award, of the Australian Institute of Physics, for her significant contribution to research at the international level. In 2022, she became a member of the College of Experts of the Australian Research Council (ARC).


Topic: GEANT4 for medical physics applications: an overview and latest updates

Geant4, which is a Monte Carlo toolkit describing particle transport and interactions in matter, is widely used in medical physics in critical applications such as verification of radiotherapy treatment planning systems, and the design of equipment for radiotherapy and nuclear medicine. It is also used in medical imaging for dosimetry, to improve detectors and reconstruction algorithms, and for radiation protection assessments.
In this seminar, an overview will be given of the capability of Geant4 for medical physics applications, focusing on the latest updates concerning Geant4 11.0. In addition, she will present the project G4-Med, which has been developed by a large international collaboration, the Geant4 Medical Simulation Benchmarking Group, including both Geant4 developers and users. The goal of the project is to perform a systematic benchmarking of the accuracy of the Geant4 physics models in a set of application scenarios of interest for medical applications.
Information will be provided on how to start to use Geant4 for medical applications. The seminar will finish by describing briefly the Geant4 development processes and Geant4 user support, which are in place to continue to develop this simulation code for and in synergy with the medical physics community.

Professor Sébastien Incerti is director of research at the National Center for Scientific Research (CNRS) and the National Institute of Nuclear and Particle Physics (IN2P3), in France. He is involved in the development of the open source Geant4 Monte Carlo toolkit ( for the simulation of particle-matter interactions. His research activities focus on the study of the biological effects of ionizing radiation in several application areas, including medical physics and space sciences, in particular for the Geant4-DNA project ( for which he has been the spokesperson since 2008. Since 2019, he is the scientific director of CNRS-IN2P3 for interdisciplinary science.


Topic: Overview of the Geant4-DNA project

In this webinar, we will present an overview of the Geant4-DNA extension ( of the general-purpose Geant4 Monte Carlo simulation toolkit ( Initially proposed by the European Space Agency, Geant4-DNA aims at simulating in a mechanistic way the biological effects of ionizing radiation on living organisms at the sub-cellular level. In particular, it allows to simulate the physical, physico-chemical and chemical stages that take place in the biological environment after irradiation, allowing in particular the prediction of early DNA damage from simplified geometries of biological targets. Geant4-DNA is fully included in Geant4 and is freely available to the scientific community. It contains examples of various applications in physics, chemistry and radiobiology, which can be used to learn Geant4-DNA. Its development continues in the framework of an international collaboration.
