Philippe Després is an Associate Professor in the Department of Physics, Engineering Physics and Optics and member of the Cancer Research Center of Université Laval, as well as a Medical Physicist at CHU de Québec and a regular researcher at its affiliated Research Center. He was trained at Université Laval (MSc 2000, Physics), Université de Montréal (PhD 2005, Physics) and University of California, San Francisco (postdoc 2005-2007, Biomedical Engineering, Molecular Imaging). He is involved in several projects encompassing hardware and software aspects of medical imaging modalities, notably low-dose X-ray imaging, advanced imaging techniques, and solid-state detectors for molecular imaging. He pioneered high-performance computing (HPC) approaches with commodity graphics hardware (GPUs) that led to innovative applications in image processing/reconstruction and radiation dose calculations, including a fast GPU-based Monte Carlo engine to simulate energy transport in matter (GPUMCD). As a HPC expert, he is also involved in data-driven research approaches, data infrastructures and FAIR-compliant research data management. In this regard, he is the Chief Data Officer at CHU de Québec – Université Laval Research Center, the Data Architect of the PULSAR health research platform, the Assistant Director of the Big Data Research Center at Université Laval, and the co-lead of the Sustainable Health axis of the Observatoire international sur les impacts sociétaux de l’IA et du numérique.
