Brief Biography
Eleanor Pullenayegum is Assistant
Professor in the Department of Clinical Epidemiology and Biostatistics at
McMaster University and a Biostatistician in the Biostatistics Unit at the
Father Sean O'Sullivan Research Centre, St. Joseph's Healthcare Hamilton--a
Division of St. Joseph's Health System. She received a PhD in Biostatistics
from the University of Toronto, then spent a year as a Post-Doctoral
Fellow at the Department of Statistics and Actuarial Sciences at the University of Waterloo. Before coming to Canada she did a BA in Mathematics at
Gonville and Caius College, University
of Cambridge, followed by the
Certificate of Advanced Studies in Mathematics, also at Cambridge. She then worked as a Research
Assistant and consulting statistician for the Centre for Applied Medical Statistics
at the Department of Public Health and Primary Care, University of
Cambridge.
Research Interests
Eleanor is interested in
developing statistical methodology for healthcare research. A particular
area of interest is in semi-parametric regression models in the presence of
incomplete data. An example where this methodology is used is in estimating
cost-effectiveness, where we often need to fit a linear regression model
for mean cost, without making additional distributional assumptions. In
this example, incompleteness arises from right-censoring. A more surprising
example occurs when fitting marginal structural models, in which the
counterfactual outcomes are, by definition, unobserved. She is interested
in comparing estimation techniques in terms of their bias, efficiency and
practicality.
