• Statistical methodology and applications focusing on resolving issues with high-dimensional data. I am interested in generalized linear modeling especially the traditional and modern approaches to select variables from a large candidate set in partial linear models, GEE, and GLMM and the development of corresponding asymptotic properties.
• Controlled randomized trials’ research as a basis for policy formulation and evaluation of existing interventions.
• Development of new procedures to model correlated observations to capture the time-varying effect with a focus on selecting appropriate correlation structure and covariates for the mean structure.
• Time series modeling of univariate and multivariate data with short-term and long-term memory behaviors as well as the development of multivariate time-series modeling techniques
• Use of Mathematics and Statistics in Predicting and Controlling Diseases
