Description of Research Expertise

Dr. Li’s methodology research interests include survival analysis, longitudinal data analysis, Bayesian methods and clinical trial design. Her current research involves statistical designs and analysis for early phase cancer clinical trials and cancer trials with multiple survival endpoints. Her collaborative research focuses on pediatric oncology, including translational and clinical trials, cancer epidemiology, and behavioral and psychosocial intervention studies.
