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.

My work deals with the computational study of the behaviour of matter at the atomic level. I am interested in how proteins are assembled into neurotoxic structures associated with degenerative diseases like Alzheimer's and Parkinson's. I also study the formation of nanostructures, such as the assembly of silicon nanowires under a gold droplet and the relaxation of disordered systems like glass and amorphous materials. All these systems are characterized by evolution at the atomic level over long periods, i.e. seconds or more. To be able to track this evolution, I am also working on the development of accelerated algorithms for following atomic movements over experimental times. The algorithms developed in my group are among the most efficient in the world, allowing us to study phenomena that are otherwise not easily accessible.

I am also interested in energy and natural resources issues, from shale gas and crude oil to mining resources. I have published a number of books for the general public on the topic, and supervised some students in this field.

In addition, I host a popular science program called La Grande Équation, broadcast on Radio Ville-Marie.

Lastly, I hold the Canada Research Chair in Computational Physics of Complex Materials.
