Research Interests

My research interests and experiences are broad, but most of my research is focused on developing statistical methods for mapping complex traits due to rare variants using second generation sequencing data. My research lead to the development of the kernel based adaptive cluster (KBAC) method for detecting associations with rare variants in case control studies. I have developed a mixed effects likelihood framework MEGA-rvQTL for quantitative trait loci mapping using unrelated individuals and pedigree samples with extreme phenotypes. I also proposed a flexible likelihood approach PLEIO-MAP for dissecting gene pleiotropy and modeling multiple phenotypes using non randomly ascertained samples. In addition, I investigated novel replication study designs combining sequencing with traditional high throughput genotyping platforms.
