Biological Sciences

The Biological Sciences program encompasses the breadth of biology from protists to plants to animals and from microbiology to ecology.

You’ll benefit from state-of-the-art laboratory facilities and the teaching and research knowledge of professors who have received provincial, national and international acclaim for their work.

In your first two years, you’ll explore the breadth of biology through lectures, labs and field studies. In the final two years, you can tailor your studies with specialized courses in areas such as biochemistry, microbiology, cell and molecular biology, genetics, entomology, physiology, neurobiology, virology, ecology, animal behaviour and bioinformatics.

Students are encouraged to participate in research through project-based courses and research assistant roles. Those who maintain an A average may pursue an eight-month Honours thesis, conducting
original research under the mentorship of a faculty supervisor — often resulting in co-authorship on scholarly publications. Outside the classroom, enrich your experience with a variety of dynamic
extracurriculars. Join a research lab, lead outreach workshops, explore career pathways through Lab Links or contribute to the innovative Lab-in-a-Box initiative. These hands-on opportunities help sharpen your skills, build your resume and connect you with a passionate scientific community.

In addition to careers in veterinary and human medicine, dentistry or pharmacy, there are many other employment opportunities.
