Research interests

Professor Zeng's research activities focus generally on the development of statistical methods of data analysis for public health and medicine and the application of such methods in a variety of public health and medical contexts.Her current statistical research interests fall into the broad areas of longitudinal data analysis and survival data analysis, with the specific areas including multi-state transitional models for longitudinal data, analysis of multivariate and clustered longitudinal data, marginal models for longitudinal data using generalized estimating equations, methods for missing data problems, methods for interval censored survival data, and model mis-specification and measurement error problems.

Education/biography

Leilei Zeng joined the Department of Statistics and Actuarial Science at the University of Waterloo as an associate professor and the Graham Trust Chair in Health Statistics in 2011.

Professor Zeng completed her BSc in Statistics from Nankai University in 1998, and then went on to receive her masters and PhD in Biostatistics from the University of Waterloo (1999-2005). Upon the completion of her graduate study, Professor Zeng worked first as a postdoctoral fellow and then as an assistant professor (2006-2011) at Simon Fraser University (SFU) with a joint appointment in the Department of Statistics & Actuarial Science and the Faculty of Health Sciences. During this time, she actively participated in the establishment of the new Faculty of Health Sciences at SFU as one of the founding faculty members, and forged several major ongoing collaborations with researchers in health sciences.

Professor Zeng was a recipient of the University Faculty Award (2006-2011) from the Natural Sciences and Engineering Research Council of Canada (NSERC). She has successfully obtained research grants from NSERC, the Canadian Institutes of Health Research (CIHR), and the Chemical Management Plan of the Government of Canada as the Principle Investigator and the Co-Principle Investigator.  Professor Zeng has been a member of the Committee on Women in Statistics (COWIS) of the Statistics Society of Canada (SSC) and also served as the SSC representative to the Caucus for Women in Statistics and to the COWIS of the American Statistical Association.
