Laboratory Medicine and Pathobiology

The Department of Laboratory Medicine and Pathobiology provides a bridge between the basic sciences and medicine. Investigating the molecular mechanisms of disease is an important priority of the department. Research is carried out in areas such as cardiovascular disease, immunopathobiology, neuropathology, and neoplasia. The department offers a Pathobiology specialist program, which gives students a broad understanding of contemporary medical research and basic scientific insights that have revolutionized our understanding of disease in recent years.

First-Year Courses

There are no specific first-year courses in Laboratory Medicine and Pathobiology.


Advice for First Year

Students interested in studying pathobiology must complete:

  • BIO 120H – Adaptation and Biodiversity
  • BIO 130H – Molecular and Cell Biology
  • CHM 135H1 – Chemistry: Physical Principles and CHM 136H1 – Introductory Organic Chemistry I (two half-courses) or CHM 151Y1 – Chemistry: The Molecular Science
  • MAT 135H1 and MAT 136H1 - Calculus I (two half courses) or MAT 137Y1 - Calculus
  • PHY 131H1 and PHY 132H1 – Introduction to Physics (two half-courses) or PHY 151H1 and PHY 152H1 – Foundations of Physics (two half-courses).



The pathobiology program is intended to train students who will go on to advance research programs in any of the diverse fields of contemporary medical research. Therefore, graduates from the program will frequently pursue graduate studies (MSc and PhD) in medical research and eventual research careers in academic, industrial, pharmaceutical, or governmental laboratories.

Knowledge of the cellular and molecular mechanisms of disease processes is also useful in a wide variety of multidisciplinary careers in government, regulatory agencies, law and environment.
