My current research focuses on transfer learning, particularly addressing challenges related to distributional shift, out-of-distribution detection, and label noise. I approach these problems through the lens of mixture models and density ratios, which are fundamental concepts in statistics.

I am an assistant professor in the Department of Statistics and Actuarial Science at the University of Waterloo in Canada. My research is on computational statistics and semi-parametric regression modelling. I have worked on methods and theory for approximate integration in statistical problems, methods for benchmark dose analysis in environmental toxicology, methods for fast Bayesian inference (without MCMC) including in spatial models, and some methods and theory for additive and random effects models.

I am an Assistant Professor in the Department of Statistics & Actuarial Science at the University of Waterloo. I work primarily on statistical analysis and methods for multiple and dynamic networks. I also have interests in post-selection inference, and formally private and fair statistical methods for network data.

Research
I am broadly interested in deep learning theory. Most recently, I have been thinking a lot about scaling limits of large neural networks and their training dynamics.

Kenneth's research interests lie at the intersection of actuarial science, statistics, and finance, with a focus on human mortality and longevity risk. The overarching goal is to develop theoretical frameworks and practical tools for modeling how people age and die, with consideration of individual heterogeneity, demographic fairness, and actuarial equity in insurance and pension design.

My research activities are primarily concerned with model uncertainty in economics, finance, and actuarial science with a focus on the valuation of financial and insurance products under model uncertainty using non-linear partial differential equations. In addition, I work on mathematical topics related to regulatory policymaking, risk measures, and mean field games.

Research Interests
My research focuses on developing novel statistical methods and theory for survival analysis to address challenges in biomedical and public health sciences. I specialize in semiparametric models for univariate and multivariate time-to-event data under right or interval censoring.

I am an Assistant Professor in the Department of Statistics and Actuarial Science. I completed a two-year Post-Doctoral Fellowship at McGill University before joining the University of Waterloo on July 1, 2022.
My research interest focuses on developing and validating statistical methods for applications in public health research, emphasizing both aggregate data and individual participant data meta-analyses of diagnostic and screening test accuracy studies. My research uses computational statistics methods such as parametric and non-parametric bootstrap approaches and deterministic and Monte Carlo expectation-maximization (MCEM) algorithms.
