One of my current research interests is to study and develop appropriate statistical methods to compare effectiveness of different treatments and procedures based on observational data such as Medicaid data and electronic health record data. My other current research interest is to study and develop statistical methods for clinical trials and high dimensional data such as  imaging mass cytometry data, and link them with clinical outcomes. My previous experience and expertise includes longitudinal data analysis, mixed effect models, generalized linear models, smoothing splines, high dimensional data analyses, modeling count data, pre-clinical studies, assessing drug interactions, and assessing drug activity in xenograft models.
