Research Interests

Missing Data, Measurement Error and Nutritional Epidemiology.

I have two primary biostatistics research activities: (1) methodology research on missing data, measurement error models, longitudinal data and survival analysis; (2) application of methods to epidemiological data.

Missing data and measurement error are very practical and interesting problems. Due to certain reasons, such as high cost, some data can only be collected for a small subsample. For example, food frequency questionnaires are commonly used to assess dietary intake for most study participants, while other instruments such as 4DFR may be subsequently administered only to a subsample of participants to reduce costs. Other factors of missing data problem may be due to the design eligibility criteria. The Women's Health Initiative's dietary intervention trial is a standard example. Furthermore, nutrients are often measured with error. Ignorance of the measurement error may sometimes dead to considerable bias to the study results.

Dietary intervention trialshave been strategies for the nutritional prevention of cancer. This leads to a covariate measurement error problem in regression models. A closely related problem arising from the regression analysis of two-stage case-control studies. To this problem, I have developed some parametric, semiparametric and nonparametric methods.

I am also interested in the missing data and measurement error problem in censored failure time data. Some work has been done in this field.

Recently, I have been working on regression analysis when the disease outcome is related to longitudinal data which are observations from a random effects model. This problem is often called joint modeling or two-stage modeling. The primary regression is to relate disease outcome to some latent covariates, while the auxillary data regression is to model covariate data.

Additional Experience

I am also interested in the missing data and measurement error problem in censored failure time data.
