Tyler Cassidy
Assistant Professor (starting in July, 2026)
(He, Him, His)
I am recruiting MSc and PhD students and postdoctoral researchers; if you are interested in graduate studies or postdoctoral research opportunities, please get in touch!
I received my PhD in Applied Mathematics from McGill University in 2019. During my graduate training, I was an intern in the Internal Medicine Research Unit at Pfizer and a Junior Fellow at the Institut Mittag-Leffler in 2018. After my PhD, I was a postdoctoral research associate in the Theoretical Biology and Biophysics Group at the Los Alamos National Laboratory. I was also awarded a NSERC postdoctoral fellowship in 2020 that I deferred to work as a Senior Scientist in the Oncology Research Department at Pfizer. I was a Lecturer in Mathematical Biology at the University of Leeds before joining UBC.
Broadly speaking, research in our group lies at the interface of mathematics, pharmacology, and medicine. Our work focuses on using predictive and mechanistic mathematical models to understand treatment response and resistance. We develop within-host models of viral dynamics in HIV and other viral infections to characterize the efficacy of antiviral therapies, investigate potential synergies of combination treatments, and quantify the emergence of drug resistance. We also develop translational mechanistic models to study treatment response and resistance to small molecules and immunotherapies in solid tumours. Ultimately, our research aims to develop quantitative frameworks to improve understanding of therapeutic response and support the rational design of treatment strategies.
I am an Academic Editor at PLOS Computational Biology and an Associate Editor at the Bulletin of Mathematical Biology.
