Current Research Interest

Delineating the complex epigenetic mechanisms that dictate cell-fate decisions as a means to discover safer and more efficient ways to rationally modulate cell identity for biomedical purposes; pursuing this research through dissecting the critical interplay among epigenetic marks, three-dimensional chromatin organization, and transcription either during maintenance of cell fate (self-renewal) or during transition to a new fate; using state-of-the-art genome-wide chromatin assays and powerful epigenetic engineering tools that enable generation and precise modulation of four-dimensional molecular road maps during cell cycle or cell-fate change
