Research Topic:                                                                            

My interest lies in the field of cellular quiescence, which is a reversible "sleep-like" state of a cell that is fundamental to tissue homeostasis/repair, aging, and cancer dormancy/metastasis. Interestingly, quiescent cells resume proliferation in different tendency upon growth stimulation, demonstrating the depth of quiescence (i.e., how deep a cell is in their dormancy) can be graded. My goal of my research is to figure out the molecular mechanisms that underlie such graded quiescence depth, and apply this understanding to modulate quiescent depth in the context of quiescence depth deregulation such as aging and cancer dormancy.
