His area of research focus concerns the development of statistical and computational methods for the analysis of high dimensional genomic data in cancer, primarily those generated by various types of high throughput sequencing experiments. He also engages in collaborative studies at the Lineberger Comprehensive Cancer Center, working with physicians and researchers on problems relating to genomics and clinical studies. Prior to coming to UNC, he was a postdoctoral research fellow in the Department of Biostatistics at Harvard School of Public Health and in the Department of Biostatistics and Computational Biology at the Dana Farber Cancer Institute.
