Louis Archambault is a researcher in medical physics. Holding a Ph.D. in Physics from Université Laval, he furthered his expertise with a postdoctoral fellowship at the M. D. Anderson Cancer Center. Joining the Department of Physics, Physical Engineering, and Optics at Université Laval in 2013, he became a full professor in 2023. The core of his research focuses on improving radiotherapy treatments through the development of new tools and the application of data science. He strives to perform accurate mapping of radiation doses used in radiotherapy and to predict the progression of cancer treatments using imaging. His laboratory, named “Clairvoyance,” aptly reflects this ambition for “viewing” radiation doses and predicting the response of treatments.

Louis Archambault is a renowned specialist in optical dosimetry. He has distinguished himself by developing new instruments for the rapid and accurate measurement of radiation doses in radiotherapy, a necessity given the increasing complexity of these treatments. Among his innovations are multipoint and three-dimensional dosimeters using hyperspectral imaging, significant advancements for mapping cutting-edge treatments in radiation oncology. These tools are applicable to all forms of radiotherapy, including proton therapy and ultra-high dose rate radiotherapy, areas of constant evolution.

His laboratory doesn’t stop at these technological innovations. It also embraces data science and artificial intelligence to integrate information from medical imaging (computed tomography, positron emission tomography, magnetic resonance imaging) into support systems for clinical teams in oncology. His work has led to the creation of a predictive system for prostate cancer, relying on an array of clinical data and imaging to determine the most appropriate treatment for a given patient. Furthermore, he has developed an innovative system to determine the optimal achievable dose distribution specific to each patient in radiotherapy, contributing to both improved quality and accelerated treatment planning processes.

In summary, Professor Archambault’s work is crucial for improving the personalization of oncological care, marking a significant advancement in the personalization and efficacy of radiotherapy treatments. These advancements aim to ensure that each patient receives the most effective treatment with the least possible toxicity.
