The Researchers


Dr. Chelsea G. Himsworth



Chelsea is a veterinarian and the lead researcher for the Vancouver Rat Project. Chelsea received her DVM from the Western College of Veterinary Medicine (WCVM) in 2007. She then went on to pursue a residency at the WCVM in veterinary anatomic pathology with a specialization in wildlife health. It was during that program that she became interested in zoonotic diseases (diseases transmissible from animals to people), interdisciplinary approaches to public health, and community-based health research. Chelsea successfully completed her board examination and became a Diplomate of the American College of Veterinary Pathologists in 2009. It was then that she decided to pursue a PhD through the School of Population and Public Health focusing on neglected zoonotic risks in urban centers. Chelsea developed this project as part of her PhD. She also works as a diagnostic pathologist for the British Columbia Ministry of Agriculture.



Kaylee Byers



Kaylee is a PhD candidate at the University of British Columbia with an interest in host-parasite relationships and animal ecology. For her doctoral research she is studying the bacterial communities associated with rat fleas to determine whether they carry any known or novel bacteria which pose a potential risk to human health. Kaylee is also evaluating how rat ecology and movement patterns may affect disease transmission by using both rat genetics and trap-and-release methods. Prior to her doctorate, Kaylee completed a Masters at the University of Alberta in evolutionary biology. She is also the organizer of Nerd Nite Vancouver, a local science outreach event.



Dr. Jamie Rothenburger



Dr. Jamie Rothenburger is a veterinary pathologist and PhD student at the University of Guelph. In 2010, she received a DVM degree from the Western College of Veterinary Medicine, University of Saskatchewan in Saskatoon. After a year practicing as a small animal veterinarian in rural Alberta, she returned to the WCVM where she completed a Master of Veterinary Science degree in the Anatomic Pathology (Wildlife Health Option). During this program, her research focused on natural diseases of rats. In 2015, Jamie achieved Diplomate status with the American College of Veterinary Pathologists. For her doctoral research, she is taking her initial work with the VRP a step further to study the associations between natural rat diseases and zoonotic pathogens. She is also exploring the relationships between environmental features and rat associated zoonotic pathogens.



Dr. David Patrick



Dr. David Patrick is an Infectious Disease Physician and Epidemiologist with posts as Professor and Director of the UBC School of Population and Public Health and as Medical Epidemiology Lead for Antimicrobial Resistance and the Do Bugs Need Drugs Project at the British Columbia Centre for Disease Control. His interest is in fostering interdisciplinary approaches to the control of infectious diseases in populations. Current expressions of this are found in efforts to track and control antimicrobial resistance and the establishment of efforts to understand the emergence and cause of new infectious diseases.



Michael Lee



Michael is a master's student in the School of Population and Public Health at the University of British Columbia. His thesis work will focus on determining how rat ecology and the urban environment affect the spread of zoonotic diseases amongst rat populations in Vancouver's Downtown Eastside. Specifically, he will assess the connection between the social isolation of adjacent rat colonies, features of the urban environment and rat-to-rat transmission of the zoonotic pathogen Leptospira interrogans. Before joining the VRP, he completed an Honours Bachelor of Science degree in environmental science with an ecology specialization in 2014 at the University of British Columbia.



Dr. Thomas Kerr



Dr. Thomas Kerr is the co-director of the Addiction and Urban Health Research Initiative at the British Columbia Centre for Excellence in HIV/AIDS, Associate Professor in the Department of Medicine at the University of British Columbia (Division of AIDS), as well as a Michael Smith Foundation for Health Research Scholar. Dr. Kerr's primary research interests are HIV/AIDS, injection drug use, health policy and service evaluation, and community-based research methods. A key focus of Dr. Kerr's work has been the scientific evaluation of Insite, North America's first safer injecting facility, and his research in this area has contributed significantly to academic, public, and government discussion, both nationally and internationally.

The Scientific Collaborators


Dr. J. Scott Weese



Dr. Weese is a veterinary internist and a professor at Ontario Veterinary College at the University of Guelph, where he received his DVM and DVetSc degrees. His interests include bacterial infections in animals and humans, methicillin-resistant staphylococcal infections, Clostridium difficile, antimicrobial resistance, emerging infectious diseases, infection control. Scott initiated the Vancouver Rat Project studies on methicillin-Staphylococcus pseudintermedius, methicillin-resistant Staphylococcus aureus, and Clostridium difficile in rats.



Dr. Ruth Miller



Ruth is a Post-Doctoral Research Fellow for UBC, based at the BC Centre for Disease Control. Ruth received her PhD from the University of Oxford, UK in 2011, where she also had her undergraduate education. Ruth's PhD focussed on Staphylococcus aureus, in particular comparison of two closely related lineages of Methicillin-resistant S. aureus (MRSA) using whole-genome sequencing. At the BCCDC Ruth leads the Chronic Complex Diseases project, which aims to use metagenomics, or the identification of microbes within a sample directly from their DNA, to investigate whether various chronic diseases of unknown aetiology have an infectious cause. For the rat project, Ruth will be analysing the whole-genome sequence of zoonotic agents identified from the urban rats, including MRSA, as well as performing metagenomic analysis of rat tissues in order to determine whether there are any undiscovered pathogens in rats.
