About me
I am an applied mathematician working at the intersection of mathematics and medicine. My research typically uses mathematical models and approaches from applied mathematics to understand how intrapatient heterogeneity drives disease progression. I am also interested in translating patient specific insights into population level treatment strategies.
I am currently a Lecturer in Mathematical Biology (UK equivalent to assistant professor) in the School of Mathematics at the University of Leeds. Before my current role, I was a senior scientist in the Oncology Research Unit of Pfizer Inc., a postdoctoral research associate in the Theoretical Biology group at the Los Alamos National Laboratory, and a Junior Fellow at the Mittag-Leffler Institute. I completed my PhD at McGill University.
As of July 1st, 2026, I will be an assistant professor in the Faculty of Pharmaceutical Sciences at the University of British Columbia. I will be recruiting MSc and PhD students; if you are interested in graduate studies or postdoctoral research opportunities, please get in touch (at tyler.cassidy ‘at’ ubc.ca).
Outside of research, I enjoy running, skiing, and cooking. The Rocky Mountains are one of my favorite places on earth and I have an ever growing to-do list of hikes. I use the pronouns he/him/his.
I am an academic editor for PLOS Computational Biology
