The major research thrusts in the laboratory are two-fold: one, development of molecular toolsets for genome, transcriptome, and proteome engineering and their application to systematic genome interpretation and gene therapy applications; and two, study and engineering of cell fate specification during development utilizing human pluripotent stem cells as the core model system. Given the parallels in phenotypes (such as self-renewal and tumor forming ability) between pluripotent stem cells and cancer cells, a key research thrust is also in dissecting aberrant cellular transformation processes such as during tumorigenesis.

Our research approach is curiosity-driven, integrating core expertise in genome engineering and stem cell engineering, with synthetic biology and materials science, and we are passionate about understanding and progressively engineering biology towards enabling gene & cell based human therapeutics.
