Clinical Specialty


Research Interests

Mechanisms of organ injury associated with acute anemia, hypoxic cellular mechanisms, nitric oxide synthase, development of blood substitutes, blood conservation

Research Activities

I am a staff anesthesiologist with a clinical focus in blood conservation. My research is focused on defining adaptive and maladaptive cerebral and cardiovascular regulatory mechanisms in experimental models of acute hemodilution. I have developed integrative whole animal models to study the adaptive physiological responses to acute hemodilution in wildtype and transgenic animals. Strong collaborative relationships have been developed within the University of Toronto with Drs. C. D. Mazer, A. J. Baker, B. Kavanagh, S. Beattie, H. Zhang (anesthesia), Dr. P. A. Marsden (medicine), Drs. Y. Yucel and N. Gupta (neuropathology), Dr. J. S. Hutchison (critical care) and Drs. L. Adamson, S. S. Bolz and S. Heximer (physiology).

Educational Activities

As a full member of the School of Graduate Studies through the Department of Physiology, I currently supervise two graduate students. I would be interested in accepting additional students interested in defining mechanisms of organ protection and cellular injury in animal models of acute anemia.
