My research is focused on statistical methods for epidemiological studies which deal with
studying factors; affecting the health and illness of populations, and serves as the foundation
and logic of interventions made in the interest of public health and preventive medicine.
The research is geared to develop novel statistical techniques for handling measurement
error in the major variable of interest, and to handle subjects with partially missing information.
The developed statistical techniques rely on parametric, semiparametric, and nonparametric
Bayesian or classical approaches for flexible and robust modeling.
 

Research interest keywords:
Bayesian methods, Errors-in-covariates, Missing data, and Survival analysis.
