Statistical Analysis of Genomic Data
Our methodological interest is in development of computational techniques for integrative analysis of genomic data sets. We have worked extensively on analysis of data from microarray-based technologies in the past, and we now focus on data from next-generation sequencing technology. We are particularly interested in ChIP-sequencing for detecting DNA-protein interactions and whole-genome sequencing to characterize copy number and structural variations. Careful analysis includes proper processing, detection of relevant feature in the data by application of appropriate statistical methods, and proper estimation of their statistical significance. For a BBS student with a strong quantitative background, joint thesis supervision with an experimentalist is an option.

Our biological focus is on chromatin structure and its relationship to gene regulation. In collaboration with several laboratories, we have profiled a number of histone modifications as well as gene expression and nucleosome positions in several model systems. We are also involved in a model organism ENCODE project in which we are mapping more than a hundred chromatin-associated proteins and histone modifications in several tissues and developmental stages of Drosophila. By computational and statistical analysis of these data, we aim to uncover the principles behind chromatin organization and epigenetic mechanisms. We are also involved in the Cancer Genome Atlas project to comprehensively characterize genomic features of multiple tumor types.
