CRM Laboratories

Mathematical Analysis
Both classical and central to modern mathematics, mathematical analysis lies at the core of our understanding of any continuous system. The mathematical analysis laboratory has undertaken in-depth studies of dynamical systems, partial differential equations and spectra of operators.

The objective of CAMBAM (Center for Applied Mathematics in Bioscience and Medicine) is the application of mathematics to address biological challenges across all levels of biological organisation ranging from the molecular/genetic through single cell and whole organ physiology to population and ecosystem dynamics.

CICMA is an inter-university research center officially established in 1989. Its research activities are concentrated on number theory, arithmetic geometry, computational algebra and sporadic finite groups.

CIRGET is a joint force of researchers at the cutting-edge of international research in differential geometry, topology, geometric group theory and mathematical physics.

GIREF gathers researchers and research groups from several academic institutions in order to facilitate research, development, training of specialists and interaction with the industrial circles in the field of modeling an numeric simulation.

Founded in 1982, LaCIM is one of the principal research center in combinatorics, algebraic combinatorics and theoretical computer science on the international scene.

Applied Mathematics
As a result of state-of-the-art computational resources, it has become possible to simulate problems and figure solutions that we only dreamed of a decade ago. This has been a driving force in the creation of this laboratory.

Mathematical Physics
Mathematical physics represents one of the traditional strengths of the CRM since the beginning of the 1970's. Research focus on several of the most active scientific areas in mathematical physics.

Montreal Institute for Learning Algorithms (MILA)
Artificial intelligence and machine learning are dynamic and ever-expanding disciplines. The incorporation of MILA into the CRM will give the CRM a more important role within the so-called “digital strategy” of the Québec government.

The work of PhysNum is focused on cerebral imaging and its method. Started within a collaboration with INSERM (Hôpital Pitié-Salpêtrière) and the Institut universitaire de gériatrie de Montréal, this trend took shape during the study of reconstruction signals in magnetoencephalographic problems.

Probability lab members pursue research in a broad range of areas, spanning theoretical and applied, continuous and discrete probability. A particular focus is on the development and analysis of probabilistic models for real-world phenomena from physics, biology, statistics and computer science.

The Actuarial and Financial Mathematics Laboratory is an inter-university group of researchers focused on the mathematics of actuarial science and finance. Its research activities are concentrated on the applications of probabilistic and statistical techniques to analyze random events with financial impact.

Statistics is central to many endeavours in society. Whether it be through surveys from sampling, clinical trials to study various biomedical treatments or experimental designs in agriculture or industry, statistical methodology can be found everywhere in science. The statistics laboratory rallies a great number of statisticians from Eastern Canada.
