Results of the Career Transition Awards Competition
The Emerging and Pandemic Infections Consortium (EPIC) is an integrated network for researchers, trainees and partners working to confront infectious disease challenges. We unite members across the University of Toronto and its hospital partners to accelerate cross-disciplinary work in the understanding and development of new countermeasures against pathogens. A key pillar of EPIC’s work is training the next generation of infectious disease research leaders that will help stop future pandemics and reduce the societal burdens of infectious disease.
EPIC Career Transition Awards support postdoctoral trainees and research associates who are ready to lead an independent project. The awards will establish a discrete fund for the recipient to facilitate an achievable, small-scale project led entirely by the applicant, while being mentored by their supervisor and a dedicated mentor in the EPIC community. This work is intended to become a cornerstone of their independent program as they develop the next stages of their career.
We are pleased to share the results of our Career Transition Awards competitions.

Project title: Sustaining and improving HIV and HCV prevention, testing, and treatment outcomes: Using implementation science to study safer supply programs
Project summary
People who use drugs (PWUD) experience a high burden of HIV and Hepatitis C, yet face challenges accessing evidence-based care. Prescribed safer supply (PSS) programs are one innovative model that shows promising evidence of improving HIV/HCV prevention, testing and treatment outcomes among the most marginalized and hardest-to-reach populations of PWUD. PSS programs deliver low-barrier and comprehensive health and social care to PWUD (e.g. primary care, infectious disease treatment, mental health counselling, housing support), alongside provision of prescribed pharmaceutical grade medications as a safer alternative to the toxic unregulated drug supply. PSS have promising potential to advance infectious disease prevention and health promotion for PWUD, but face major barriers to long-term sustainability and scale-up. Using an implementation science framework and mixed-methods approaches, this study will explore contextual factors theorized to influence the sustainability of PSS programs and related infectious disease outcomes. Research will be conducted at a Health Canada-funded prescribed safer supply program. Data collection will include quarterlyextracts of program-wide indicators, participant observation, surveys, and in-depth interviews with PSS prescribers and clients over a one year period when they will be transitioning from a pilot phase (funded by Health Canada) to long-term sustainability. This study will generate timely and actionable evidence to inform sustainability planning at this critical juncture, including guidance on how PSS programs may be sustained within pilot organizations and scaled-up within the broader health system.

Project title: Using stem cell-derived macrophages to combat pulmonary viral infections
Project summary
Influenza A Virus (IAV) – or more simply “flu” – is the primary infectious agent that causes our seasonal flu outbreaks and can lead to pandemic level health emergencies due to seasonal strain changes and lack of population immunity to them. Though advances have been made over decades to supply health care systems with vaccines, very few new disease treatments or preventions have been established. My project focuses on a new experimental approach whereby we have developed a specialized immune cell from stem cells – specifically adapted to function in the lungs – that inactivates respiratory viruses in viral lung infections and reduces viral lung disease in animal experiments. For this project, I am seeking to test the ability of this special stem cell-derived immune cell to inactive the flu virus and reduce respiratory disease in experimental animals infected with flu (IAV). I plan to test and compare how these cells inactivate different strains of flu. By researching these cells in experimental animals and then translating our knowledge of them to the human immune cell counterpart we will be able to understand the mechanisms by which these cells inactivate respiratory viruses. This information can be used to modify the cells to create viral therapeutics that reduce respiratory viral diseases in humans, including the virus that causes COVID, and lower the burden on health care systems. This project will establish the research platform from which I will broaden its application during my future career development.

Project title: The impact of bacterial cell signalling on anti-phage defence in Pseudomonas aeruginosa
Project summary
Bacteria are becoming increasingly resistant to antibiotics, leading to 1.27 million deaths worldwide this year. There is an urgent need to develop effective new treatments for these infections. Bacteriophages, small viruses that are natural predators of bacteria, provide an attractive alternative for therapeutic use. However, as bacteria encode many defence systems to protect them from phage infection, a more thorough understanding of phage-bacteria dynamics is required before they can be effectively deployed. My work will focus on Pseudomonas aeruginosa, a notoriously difficult to treat human pathogen. I will create a comprehensive library of all anti-phage defence systems in P. aeruginosa, and these systems will be monitored for changes in expression in the presence of bacterial signaling molecules. This will establish whether bacteria communicate to warn each other of impending phage infection, and if those signals drive expression of anti-phage defence systems. This is the first comprehensive study to examine how bacteria respond to phage infection and ultimately protect themselves. The knowledge gained in this study will allow us to develop highly effective phage therapy treatments.
