Brief Biography

Juthaporn Cowan is an Associate Scientist at The Ottawa Hospital Research Institute, Assistant Professor at The University of Ottawa, cross-appointed Assistant Professor at the Department of Biochemistry, Microbiology and Immunology and a Physician for the Division of Infectious Diseases at The Ottawa Hospital.

Dr. Cowan began her training at Mahidol University in Thailand for her MD. She also obtained a PhD in Microbiology and Immunology at Kyoto University in Kyoto, Japan. She completed a Postdoctoral Fellowship at The Ottawa Hospital Research Institute. Her research at the time focused on Tuberculosis and immunopathogenesis. She then started her Internal Medicine training at the University of Ottawa. During her postgraduate training her interest shifted from tuberculosis to infection in immunodeficiency patients. Subsequently, she completed a Clinical Fellowship in Infectious Diseases with the University of Ottawa.

Drs. D. William Cameron and Cowan run an immunodeficiency/immunoglobulin treatment clinic in Ottawa. The clinic is expanding and is served as a resource for clinical research.
