Back Qian (Vivian) Liu, PhD Viral Zoonoses Assistant Professor, Institute of Parasitology, Faculty of Agricultural and Environmental Sciences, McGill University Zoonotic diseases (zoonoses) are infectious diseases that originate from animals and subsequently infect humans. RNA viruses are the primary etiological agents of human emerging pathogens, occupying up to 44% of all emerging human diseases. Paramyxoviruses are negative-stranded RNA viruses with great zoonotic potential. Members include established human pathogens (e.g. Measles virus) and emerging deadly zoonotic viruses (e.g. Nipah and Hendra viruses). My lab is interested in understanding the infection and transmission of zoonotic viruses in humans and animals. Specifically, we study the mechanisms of virus entry and assembly and how viruses hijack and/or evade host factors during these processes. By combining super-resolution imaging, novel fluorescence labelling, and optogenetic tools, we provide precise structural and behavioural information to dissect virus-host interactions during viral infection and transmission. Our research sheds light on novel antiviral development. Learn More

We pair the discipline-based research skills our trainees acquire during their traditional thesis research work with the advanced systems thinking needed to develop, evaluate, and modify context-specific policies to prevent and control the spread of FWVZ pathogens. The Policy Challenge Each year, our collaborators and co-applicants assemble a unique case study based on real-world public health challenges involving FWVZ pathogens. These case studies form the basis of our Annual Policy Challenge, a year-long project culminating in a five-day all-expenses-paid retreat, where w e challenge our trainees, working in interdisciplinary teams, to pitch innovative policy solutions and outreach strategies to a panel of leading stakeholders in government and industry. Our Second Annual Policy Challenge For our Second Annual Policy Challenge, Masters and PhD trainees joined forces in four unified teams, each tackling a unique public health challenge, all centred around the increasingly focal issue of pathogen monitoring in wastewater. To learn more about the four challenge questions and the context behind them, check out our Participant's Guide . (Pictured below, attendees of the second annual retreat) 2025 Participant's Guide Policy Solutions Four hybrid teams of Master's and PhD trainees were asked to propose policy briefs addressing the issue of wastewater monitoring for pathogens. You can read their proposals here. Team 1: Evidence-Based Wastewater Surveillance: Guiding Municipal Policy for Public Health and Environmental Monitoring Fiona Hui, Hesham Adam, Marie-Zoé Lapierre, Parichay Subedi, Rafael Fernandes Ferreira, Salomé Plat, and Sarah Donald Team 2: Wastewater Monitoring of Incoming Aircraft at Canadian Ports of Entry Alla Yushchenko, Ben Sakdinan, Cody Malone, Kyle Story, Paul Glenn, Pierre-Luc Longchamps, and Taylor Volappi Team 3: The Identification of Cryptic Viral Lineages in Wastewater: Protecting the Privacy of Canadians in Wastewater Surveillance Gillian Cameron, Giuliana Leonarda Matta, Jinha Suh, Melika Amoueian, Natalia Lorenc, Yihan He, and Yuxiao Lu Team 4: Validation and Approval of Measles (Morbillivirus Hominis ) Wastewater Monitoring Methods Alexandra Foley-Eby, Amanda Williams, Cody Koloski, Ivan Drahun, Kira Mudrey, Kirsten Campbell, and Yuxin Hu Our First Annual Policy Challenge Our first Policy Challenge was a year-long activity, culminating in a week-long retreat hosted at McGill's Gault Nature Reserve. The event featured speakers from organizations like Health Canada, the Office of the Chief Science Advisor, and the Smithsonian National Museum of Natural History, alongside prominent voices from academia. The last day of the retreat was punctuated by final presentations from our PhD and Masters students, showing off their policy proposals and promotional media. The Question Lecture Slides Lecture Recording An effective human vaccine against Lyme disease has existed since the mid 1990's. However, the anti-vaccine movement and subsequent disappointing vaccine uptake led the manufacturer to discontinue its commercial production. Thousands of people are now needlessly suffering from Lyme disease and symptoms associated with post-Lyme disease. While new vaccines are currently in stage three clinical testing, some fear they may meet the same fate. What public policies need to be put in place in Canada to ensure access to safe and effective vaccines against Lyme disease for those who want to be immunized? Policy Solutions Three teams of our PhD trainees were asked to propose policy solutions addressing the issue of Lyme disease vaccinations. You can find the policy briefs they created to pitch their proposals here. Lyme Disease Vaccine for Canadians: Policy Brief Ivan Drahun, Alexandra Foley-Eby, Cody Koloski, & Yuxiao Lu Lyme Disease Prevention: Enhancing Vaccine Access and Public Awareness Initiatives Gillian Cameron, Fiona Hui, Natalia Lorenc, & Alla Yushchenko Towards Trust: Policy Initiatives for Vaccine Confidence through Transparency and Education Audrey Corbeil, Rafael Fernandes Ferreira, Cody Malone, & Taylor Volappi Promotional Media Our Masters' students were tasked with creating promotional media, with three students paired with PhD teams to promote their policy proposals and one student promoting Lyme awareness.

Open to graduate students at participating schools, NSERC CREATE in One Health Against Pathogens (OHAP) was established to train experts in interdisciplinary research, communication, and crafting effective public policy. The One Health Crisis Food-borne, water-borne, vector-borne, and zoonotic (FWVZ) pathogens have been on the rise in Canada and around the world with the explosion of globalization, antimicrobial resistance, and climate change. All models predict the burden of FWVZ pathogens on human health is unsustainable, and will worsen as the effects of climate change intensify.To control the spread of FWVZ pathogens, we must integrate research, surveillance systems, and public policies in a holistic ‘One Health’ approach. One Health recognizes the profound interconnections between human, animal, and environmental health while providing effective, equitable, and sustainable ways to maximize public good and minimize harmful social, economic, health, and environmental outcomes. The current political and social landscape does not encourage the dissemination of difficult facts or the adoption of sound science-backed public policy. Scientists must learn to effectively and accessibly communicate facts and evidence with politicians and the general public. NSERC CREATE in One Health Against Pathogens (OHAP) was established to train experts in interdisciplinary research, communication, and crafting effective public policy. With these skills and our holistic One Health approach, our graduate students will have what it takes to bring an end to our current global health crises and support the development of preventative technologies and policies to safeguard our shared future. We acknowledge the support of the Natural Sciences and Engineering Research Council of Canada (NSERC). Nous remercions le Conseil de recherches en sciences naturelles et en génie du Canada (CRSNG) de son soutien.

Back Sebastien Faucher, PhD Water-borne Pathogens Associate Professor, Department of Natural Resource Sciences, Faculty of Agricultural and Environmental Sciences, McGill University Prof. Sebastien Faucher’s research program aims to understand the genetic factors and environmental factors that influence the survival and growth of water-borne pathogens in the non-clinical environment and their transmission to humans. The emergent pathogen Legionella pneumophila is the prime focus of this research program. This pathogen grows in engineered water systems. Metagenomic tools are used to understand the role of the resident microbiota and the genomic diversity of L. pneumophila . The effect of climate change and water system operation and disinfection strategies on the evolution of L. pneumophila is also studied through experimental evolution in model water systems.

The causative agent of Lyme disease, Borrelia burgdorferi , often consists of many genetically distinct strains. One of my main research interests is understanding how this strain diversity is maintained in nature. Our research is currently focused on three topics: Variation in host tissue abundance, transmission, and pathology among strains of B. burgdorferi ; Ability of maternal antibodies to protect offspring from infection with B. burgdorferi ; and Multiple-strain infections and interactions between strains in the host or tick vector.
