Eleanor Pullenayegum, PhD
Eleanor Pullenayegum, PhDSenior Scientist
Eleanor is a biostatistician whose primary work focuses on developing methodology for longitudinal data and health economics. She trained at the University of Cambridge (BA and MA in mathematics), the University of Toronto (PhD in Biostatistics with Dr. Andrew Willan) and the University of Waterloo (postdoctoral fellowship with Dr. Richard Cook). She worked as a consulting biostatistician at the Department of Public Health and Primary Care at the University of Cambridge before coming to Toronto to pursue her PhD. Before assuming her current position at SickKids, she was on faculty at McMaster in the Department of Clinical Epidemiology & Biostatistics. When she is not working, Eleanor’s favourite activity is taking her daughter to the splashpad or playground, or just joining her wherever her sweet little imagination leads.

Teresa Tsui, PhDResearch Associate
Teresa’s research interests are in developing health economic methods, including the use of real-world health utilities to inform clinical and policy decisions. Her Research Fellowship is co-supervised by Kelvin Chan at the Canadian Centre for Applied Research in Cancer Control (ARCC) and Eleanor Pullenayegum at the Hospital for Sick Children. Teresa completed her PhD in Pharmaceutical Sciences at the University of Toronto, and Toronto Health Economics and Technology Assessment (THETA) Collaborative with Murray Krahn and Aileen Davis to develop the core of a novel breast cancer preference instrument. Teresa has a BSc(Hon) in Pharmacology (specialist) and Psychology (minor) and MSc in Pharmaceutical Sciences, both from the University of Toronto. Her MSc was in understanding the role of patient values in decision making. She has worked at the University of Toronto as a Research Manager, lecturer, and small group facilitator. In her spare time, Teresa enjoys cooking, yoga, and music.
Larry Dong
Larry DongGraduate Student
Larry is a PhD student in biostatistics jointly supervised by Dr. Olli Saarela and Dr. Eleanor Pullenayegum. He previously completed both his BSc in mathematics and MSc in biostatistics at McGill University and an MSc in Public Health Data Science at the University of Bordeaux. His PhD thesis revolves around the estimation optimal treatment regimes with irregularly observed data. He is also passionate about open-source software, as he currently serves as a GitHub Campus Expert, and regularly contributes to PyMC, a Python package for Bayesian modelling. Outside of school, he enjoys skateboarding, playing volleyball and eating fruits, especially grapes, bananas, oranges, watermelon and nectarines.
George Stefan
