Current Positions

  • Associate Professor, Division of AIDS, Medicine
  • Director, Laboratory Program, British Columbia Centre for Excellence in HIV/AIDS
  • Glen-Hillson Professor in Clinical HIV Virology, The University of British Columbia
  • CIHR/GSK Research Chair in HIV/AIDS at the University of British Columbia

Research Interests

The primary goal of the basic research program is to provide novel virological and drug information for HIV-infected British Columbians receiving antiretroviral therapy. Key priorities include understanding and preventing HIV drug resistance, the development, application and evaluation of innovative cost-effective laboratory tests that monitor HIV therapy response and antiretroviral drug toxicities, improving drug adherence through the development and application of laboratory-based tools that accurately detect and report non-adherence, investigation of the relationships between human and viral genetic factors and treatment outcomes, and therapeutic drug monitoring. The research laboratory team includes individuals with expertise in virology, genomics, chemistry, molecular biology and quality assurance systems.
