Faculty of Science


Westerns Science offers 8 departments and 2 major inter-faculty programs. A brief overview is provided here. We encourage you to discover the specialized research and training each department offers.

Our Departments

Applied Mathematics

Applied Mathematics

The Department of Applied Mathematics cultivates a broad knowledge of basic and applied mathematics while developing skills in the use of numerical and computational methods. The expertise acquired in Applied Mathematics is useful to solve complex problems in the natural, social and applied sciences. Areas of specialty include theoretical chemistry, quantum systems, bioinformatics, fluid mechanics, finance, computer science, environmental modeling, and environmetrics.


Biology Department

Biology at Western is an exciting, dynamic and broad-ranging subject that addresses the complexity of living organisms and encompasses topics such as the role of specific genes in embryo development, flowering or behaviour, and broad-scale interactions between organisms in ecosystems and the environment.


Chemistry Department

Chemistry is the study of the elemental composition, structure, properties and reactivity of atoms and molecules. From the simplest gaseous element to complex structures such as proteins, chemistry impacts all aspects of everyday life. Chemists strive to understand and control the fundamental structure-property relationships of molecules. Building on this foundational knowledge they develop new materials for applications in areas such as life and health sciences, pharmaceuticals, nanoscience, electronics and next generation environmental initiatives (fuel cell and solar panel technology for example).

Computer Science

Computer Science

Computer science provides a foundation enabling graduates to adapt to new technologies and ideas in an information-driven world. From designing and building software to developing effective ways to solve computing problems and providing new approaches to cybersecurity, computer science at Western addressing challenges in diverse areas such as game development, medical imaging, social and mobile computing, or bioinformatics. In 2016, the Princeton Review named Western Computer Science among the top destinations in the world to study game design.

Earth Sciences

Earth Science Department

Earth Science at Western focusses on addressing the structure and dynamic character of the Earth's interior, the evolution of life and our ever-changing climate, the formation and geology of our planet and its relation to other bodies in the solar system, and the occurrence and management of the precious natural resources on which our twenty-first century society depends on.



Mathematics is the rigorous study of quantity, structure, space and change. which appear in all forms of scientific inquiry. Western Science examines several areas of contemporary mathematics including algebra, analysis and analytic geometry, homotopy theory, and noncommutative geometry. 

Physics & Astronomy

Physics and Astronomy

Physics is the study of nature at its deepest level. From theoretical to practical physics, Western Science is exploring its applications to medicine, planetary processes, the utility of nanotechnology, and material sciences. Astronomers at Western are seeking to understand the nature of the universe and its constituents. Through visible to short-wave telescopes and large-scale computer simulations to department scholars contribute to our understanding of the universe.

Statistical & Actuarial Sciences

Statistical & Actuarial Science

The analysis of big data through mathematical and probability modeling allows us to answer the questions facing all aspects of society. Statistical & Actuarial Science scholars are leading efforts to create predictive models addressing issues in finance, healthcare and environment and sustainability.
