Head of the Vaccine Research Laboratory, BC Centre for Disease Control Professor, Department of Medicine, University of British Columbia


Dr. Robert C. Brunham is the Head of the Vaccine Research Laboratory at the BC Centre for Disease Control (BCCDC). Until 2014, he was also the Executive and Scientific Director of the BCCDC. Dr. Brunham is also a Professor of Medicine at The University of British Columbia. He has over 350 publications and an h-index of 55, as calculated by ISI’s Web of Knowledge. He is internationally regarded as an expert on infectious diseases and widely known for his research on Chlamydia, SARS and HIV.

In 2005 Dr. Brunham received the CIHR Partnership Award for exemplifying research excellence by bringing health research communities together. His belief in seeking fundamental understanding of scientific problems while maximizing their benefit to society has been characterized by a career of partnership across the broad breadth of medical biosciences including molecular biology, clinical investigation and public health studies.

In Chlamydia research, Dr. Brunham is a world authority. He has made seminal contributions to defining the clinical features of infection in women, evaluating the impact of screening and treatment control programs, determining the underlying mechanisms of immunity, and discovering protective antigens suitable for vaccine development. He has innovatively analyzed the impact of public health efforts to control Chlamydia, deduced that the strategy is arresting the development of immunity and developed the rationale that a vaccine will be essential to Chlamydia control.

Dr. Brunham is well known for his work in elucidating the SARS genome, defining the characteristic clinical features of SARS infection and tracing its distinctive epidemiology to underlying network transmission dynamics. Using team science, he collaborated in accelerating the successful development of a vaccine for SARS.

Dr. Brunham’s contribution to understanding HIV is significant. He collaborated in determining the major role of chancroid in concentrating accelerated HIV transmission among high-risk groups in Africa and the major role of HLA molecules in HIV resistance and susceptibility.

Senior Scientist, BC Centre for Disease Control

Adjunct Professor, Chemical and Biological Engineering Department, UBC

Marko Kryworuchko.jpeg


Dr. Kryworuchko is an Immunologist who joined the BCCDC and UBC in 2017. His research aims to better understand host-pathogen interactions at the cellular and molecular levels with the ultimate goal of developing new and more effective infectious disease therapeutics and vaccines. Recent efforts have been focussing on the cellular autophagy or "self-eating" pathway.  Autophagy, as its name suggests, allows the cell to engulf and degrade portions of its cytoplasm for use as an energy source, and to remove superfluous or defective organelles and proteins. However, the autophagy machinery of the cell is also critical for the elimination of certain intracellular pathogens such as Mycobacterium tuberculosis and HIV. Autophagy signals the presence of pathogen to the immune system, and mobilizes innate and adaptive immune cells including monocytes/macrophages, helper and killer T cells, as well as antibody-producing B lymphocytes. Projects at the BCCDC are evaluating autophagy-based therapeutics and vaccines against pathogens of major public health importance including Chlamydia, Salmonella, Carbapenem antibiotic resistant bacteria, and others.


Dr. Kryworuchko obtained his PhD in Microbiology and Immunology at the University of Ottawa. His thesis described molecular mechanisms regulating the expression and function of the cellular adhesion molecule CD44 in normal as well as Epstein-Barr Virus-infected and immortalized B lymphocytes. Subsequently, as a post-doctoral fellow at Institut Pasteur (Paris, France), he pursued interests in HIV immunopathogenesis, elucidating virus-induced defects in CD4 helper and CD8 cytotoxic T lymphocyte responses. Prior to joining the BCCDC, he has worked extensively in the areas of viral immunopathogenesis, programmed cell death, and vaccine R&D at the University of Saskatchewan, the University of Ottawa, and the Children's Hospital of Eastern Ontario.

Dr. Danuta Skowronski 

‎Dr. Danuta Skowronski is Epidemiology Lead responsible for surveillance, rapid response research and program/policy recommendations for Influenza and Emerging Respiratory Pathogens at the BC Centre for Disease Control (BCCDC). She has been recognized for her notable contributions around several major public health events such as SARS, avian influenza, the 2009 H1N1 pandemic, enterovirus D68 and for regular expert guidance around seasonal influenza—an annual re-emerging pathogen.

Dr. Skowronski is credited with having pioneered the test-negative design (TND), an epidemiological innovation for monitoring how well the annually reformulated influenza vaccine protects each year. The TND was recognized by Accreditation Canada in 2015 as an Innovative Leading Practice and has since revolutionized global capacity to monitor influenza vaccine benefits. Adopted by multiple countries worldwide, TND findings are now used twice each year by the World Health Organization to inform influenza vaccine strain selection in both hemispheres.

Dr. Skowronski has more than 130 publications, primarily related to influenza, and has participated in numerous provincial, national, and international expert advisory committees. She is regularly sought by the media for her thoughtful, calm and clear communication on influenza and other emerging pathogen issues.

Among her various recognitions and distinctions, Dr. Skowronski has received Awards of Excellence for contribution to Public Health from the BC Provincial Health Officer, and for contribution to Quality of Life from the BC Pharmacy Association. She was named Woman of Distinction in delivering the 15th Hycroft Lecture for the University of BC's Women's Club of Vancouver. In 2007, she was recipient of the University of BC President's Award for Public Education through Media and in 2010, the Vancouver SUN similarly recognized Dr. Skowronski, naming her among the 100 most influential women of BC. In 2011, she was awarded the James M. Robinson Award by the University of British Columbia, Faculty of Medicine for her significant contributions to public health and in 2015 her team was recognized for providing Excellence through Knowledge in receiving the Provincial Health Service Authority (PHSA) + Award. In 2016, the Georgia Straight featured Dr. Skowronski among five leading women making a difference in the health of Vancouver residents.

Dr. Skowronski completed her medical degree and family medicine training at Queen's University in Kingston, Ontario and completed a Master's of Health Sciences degree and a Fellowship in Community Medicine at the University of British Columbia. She is further certified with the American Board of Preventive Medicine and completed additional training with the London School of Hygiene and Tropical Medicine.
