Research Interests

Dr. Hu's statistical research has primarily been in methodological developments for handling complex data. Her contributions in the area include pseudo-likelihood based and estimating function approaches with supplementary information. Growing from her early work on incomplete event history data, such as censored/truncated lifetimes and panel counts, Dr. Hu's current interests are in various imperfect stochastic process data. Her on-going projects include analyses of longitudinal data with latent classes and marked point processes with spatial correlations. Another research area is statistical monitoring in clinical trials. Motivated by an ACTG clinical trial, she proposed the repeated confidence bands approach for interim reviews jointly with Steve Lagakos.

Dr. Hu has collaborated with investigators in a variety of research fields, such as HIV/AIDS, cancer, public health, reliability, forest fire management, political science and marketing. She enjoys identifying statistical problems from real-life projects and developing approaches to dealing with the issues. Her ongoing collaborative projects include the ones from the pediatric mental health program at University of Alberta and from the opioid agonist treatment (OAT) for opioid use disorder (OUD) program at BC Centre for Excellence in HIV/AIDS.
