• Modeling of radiation transport coupled to magnetic fields by the Monte Carlo method.
• Characterization of tissues by spectral computed tomography.
• Small field dosimetry.
• Simulation of the dosimetric response of detectors.
• Radiation detectors: ionization chambers, radiochromic film, diodes, scintillator, liquid ionization chamber.

Delphine Bouilly and her team assemble ultra-miniature electronic circuits and sensors to explore the dynamics of the interactions between biological molecules (DNA and proteins) or the fluctuations within a single molecule. The goal is to develop new tools to identify biomarkers associated with various types of cancer and to improve our understanding of the mechanics of basic macromolecules.

Improvement of radiation oncology treatments. The presences of specialized equipment in the department of radiation oncology (linear accelerators, computed tomography scanner, positron emission tomograph, brachytherapy suites) enables the development of projects which often have direct clinical applications.

Directs a research group of graduate students and interns from the department of physics and École Polytechnique. Students are located in the radiation oncology department in the Hôpital Notre-Dame du CHUM and work regularly with clinical personnel; i.e., clinical physicists, radiation oncologists, and technologists.

  Dr. Gaudreault’s expertise notably spearheaded him to develop an integrated innovation Green Chemistry approach based on recycled fibres. His scientific and applied background helped developed strong partnerships between academia and industry. He has been a member of the Centre in Green Chemistry and Catalysis (CGCC) since 2011 and associate member of the Quebec Centre for Advanced Materials (QCAM) since 2018.

  Dr. Gaudreault’s scientific interests include; green chemistry, Alzheimer's Disease, COVID-19, molecular modelling, kinetics of colloids, chemistry of pulping/bleaching and papermaking, recycling, corrosion inhibition, biomolecules and biomaterials.
