Bio

Juthaporn Cowan is an Associate Scientist at The Ottawa Hospital Research Institute, Associate Professor at The University of Ottawa, Division of Infectious Diseases, Department of Medicine and Department of Biochemistry, Microbiology, and Immunology. She is an Infectious Diseases physician 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 completed Internal Medicine and Adult Infectious Diseases training at the University of Ottawa. 

Dr. Cowan is the medical lead for the Ontario Immunoglobulin Treatment Program (ONIT). The ONIT Program is a Ministry of Ontario approved initiative to improve the healthcare of patients with immunodeficiencies requiring immunoglobulin replacement therapy. This clinical program is set out to support immunoglobulin replacement therapy through home, self-administered subcutaneous immunoglobulin (SCIG) infusion. That Support is provided through hospital-based outpatient clinics with nursing coordination. The main objectives of the program are to provide consistent, standardized diagnosis and management of immunodeficiencies requiring immunoglobulin treatment.  

Dr. Cowan has served as co-lead of the special immunization clinic network of the Canadian Immunization Research Network since 2023. Her dedication and contribution to immunization in immunocompromised patients is recognized locally and nationally.
