Dr. Xiao’s research focuses on developing genomic technologies and applying them in studying the human genome. Among his recent work at Drexel is the development of technologies based on the CRISPR-Cas9 system for genome mapping and sequencing, which have broad applications in molecular diagnostics, cell/gene therapies, and faster cancer screening. Using this and other technologies, they have gained many significant insights into human genome structures and variations.
