My primary research focuses on the applied statistical methodology and data analysis. I am particularly interested in statistical process control, reliability and survival modeling, statistical methods for environmental study, data visualization and statistical data mining. I am also interested in working with researchers in other disciplines on the applications of advanced statistical modeling.

I am interested in projects from almost all areas that involve significant statistical components. I usually work with collaborators / clients closely throughout the entire phase of consultation: from the initial stage of sampling and study design to modeling, outcome interpretation and the writing of formal and rigorous statistical report including both technical justifications and practical interpretations.
A partial list of models involved in numerous projects completed in last few years include linear regression models, binary logistic regression model, family of multi-category logit models, Poisson and loglinear regression models, lifetime regression models (non-parametric Kaplan-Meier, semi-parametric Cox proportional hazard and various parametric models including accelerated failure time and competing risk models) based on both censored and completely observed data, time series modeling (exponential smoothing family of models, ARIMA and ARIMAX) and various random-effect regression models (including repeated measure ANOVA) for longitudinal data, models with high dimensional data (principal component analysis, factor analysis and structural equation modeling), linear and nonlinear discriminate analysis, cluster analysis, etc.
