University Health Network has grown to be one of the largest research and teaching hospital networks in Canada - pioneers in improving the lives of patients. Our long history of health professions education at Toronto General, Toronto Western, Princess Margaret and Toronto Rehab hospitals has consistently advanced the science of education.
University Health Network is a health care and medical research organization in
Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international
source for discovery, education and patient care.
Being touched by illness affects us in different ways. Many people want to give back to the community
and help others. At UHN, we welcome your contribution and offer different ways you can help so you can find one that suits you.

Dr. Behrang Keshavarz started a postdoctoral fellowship at the KITE Research Institute at UHN in 2012, the team had a specific job in mind for him.
It was developing DriverLab, a driving simulator that includes a 360-degree projection system with immersive view, surround sound and additional features, such as an eye-tracking system and rain simulator. It was the first of its kind in Canada and aids research surrounding safe driving and vehicle collisions.
The team was aware of the potential for research participants to experience motion sickness in these types of simulators, so Dr. Keshavarz was tasked with studying ways to potentially control, or at least minimize, the side effects experienced in these instances.
Over the past 10 years at KITE, Dr. Keshavarz's research footprint has expanded beyond DriverLab, mostly because motion sickness isn't confined to a driving simulator.
Similar issues also occur in StreetLab, another simulator based at KITE's Challenging Environment Assessment Laboratory (CEAL). Users of StreetLab are fully immersed in an audio-visual simulation that replicates downtown Toronto, including cars and pedestrians.
Another lab Dr. Keshavarz works in is called PerceptionLab. It is arguably the simplest of the group, but the most important to Dr. Keshavarz's everyday research.
Screens, projectors and a head-mounted display (virtual reality headset) are available for research use. It's a small but crucial space in the study of motion sickness related to virtual reality and visual stimulation.
"A lot of things I investigate don't necessarily need highly sophisticated or advanced laboratories," says Dr. Keshavarz. "You can induce symptoms in a very simple fashion in an effective way and then try to minimize it."
