Research Interests

Dr. Hu's statistical research has primarily been in methodological development for handling data with complex structures. 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 unconventional point process data. Her on-going projects include analyses of longitudinal data with latent classes and marked point processes with spatial correlations.

Dr. Hu has collaborated with investigators from a variety of research fields, including HIV/AIDS, cancer, public health, reliability, forest fire management, psychology, political sciences, sports analytics, and substance use disorder. She enjoys identifying statistical problems from real-life projects and developing approaches to dealing with the challenges.
