Research Interests

My research interests include the development and application of statistical methodologies in the area of sleep medicine epidemiology. Sleep disorders impact large fractions of the populations. I am interested in developing methods to elucidate the complex inter-relationship between cardiovascular diseases and sleep disorders, and to identify novel targets for cardiovascular disease reduction that related to common, treatable sleep disorders, using data from clinical trials and epidemiological studies. In the analysis of clinical trials, it is often important to investigate whether treatment effects vary among group of patients defined by patient characteristics.

Currently I am working on developing statistical methodologies to recommend treatment that optimizes the outcome for each individual. In addition, I am also interested in the design and analysis of cluster randomized trials, where a group of subjects, as opposed to individuals, are randomized to each of the treatment arms in the trial. The particular questions I am addressing include how the complex correlation structure within clusters affects the sample size and power of the trial, and how to analyze data from such trials efficiently, taking into account the correlation structure and the issue of missing data.
