Research

 

I am interested in survival and longitudinal Modeling, multilevel (hierarchical) Bayesian Inference, MCMC and genetic epidemiology. My work is inspired by and applied to biomedical and epidemiological studies.

Research Experience


PhD dissertation research (Aug 2005 - May 2008)

  • Project Title: Longitudinal cohort of Alpha-Tocopherol, Beta-Carotene (ATBC) Lung Cancer Prevention Study

The major goals of this study are (1) to identify and quantify baseline factors associated with success of permanent smoking cessation and describe the full stochastic nature of the smoking addiction pattern; and (2) to design computational practical methods for dealing with the size of the data set and complexity of the models. The study involves sophisticated modeling of detailed longitudinal data on multiple related phenotypes. Further complexities arise due to nested ¡°case-control¡± sampling for collection of the genotype data. I am currently developing novel statistical methodologies for analysis of this kind of data under the co-supervision of Drs. Ciprian Crainiceanu and Thomas Louis from the Biostatistics Department, John Hopkins University, and Dr. Nilanjan Chatterjee in National Cancer Institute (NCI).
