Research is a team activity at the OHRI, involving scientists, clinical investigators, trainees and specialized support staff. Patients also play a crucial role in research by volunteering for studies and providing inspiration and ideas for improving care.


OHRI has 110 scientists leading teams of five to 30 people each. Scientists have MDs, PhDs, or both, and spend the majority of their time on research. All OHRI scientists are also professors at the University of Ottawa and many are active physicians at The Ottawa Hospital.


Investigators are generally physicians, nurses, or other health-care professionals at The Ottawa Hospital. They devote significant time to research while also being very active in clinical practice. OHRI has more than 400 investigators.


OHRI has about 400 trainees who conduct much of the hands-on research at OHRI and come up with many of the innovative ideas for new studies. Trainees include graduate students, postdoctoral fellows, undergraduates, summer students and volunteers. Most are undertaking research at OHRI as part of a degree at the University of Ottawa.

Support staff

OHRI depends on more than 800 highly specialized support staff to conduct groundbreaking research. Support staff members coordinate clinical trials, manage research programs and operate sophisticated laboratory equipment. They also take care of health and safety, commercialization, finance and other areas of administration.
