The long-term research interest of my laboratory is to understand the mechanisms and consequences of human genomic variation, with a focus on mobile DNA elements, and human disease. We will combine computational and experimental tools to perform genome-wide analyses on human genomic variation. Current research in my lab includes three major areas: understanding mobile element biology, investigating human demographic history and population diversity, and identifying disease-causing genes using genome-wide data.
