Dr. Li's main research is in the area of developing statistical methods for the analysis of clinical trials and epidemiologic studies in which the time to an event is a primary outcome. He has worked in nonparametric regression, model selection, nonparametric and semiparametric likelihood ratio based inference, two-sample problems, and bootstrap for censored, truncated, and biased data. Recently he has been studying resampling methods in nonparametric censored regression. He has also been working on semiparametric estimation of survival probabilities for incomplete cross-sectional data which arise frequently in prevalent cohort studies.
