Research Interests
My research interests are in the development and application of statistical methods for clinical and biomedical research, with a focus on survival analysis, regression modeling, and the design and analysis of clinical studies. My methodological research includes statistical modeling of censored survival data and the evaluation of clinical outcomes. My interdisciplinary research encompasses the area of oncology, reproductive and women health, pulmonary fibrosis, and sleep and healthcare quality where we address complex clinical research questions through observational studies, clinical trials, and electronic medical records data.
