Research Interests

Understanding the quiescence program and its benefits for stem cell function.Most cells in adult tissues have permanently ceased proliferation. However, stem cells in regenerating tissues must attain and maintain a temporary state of quiescence so that a reserve pool is available for future unpredictable bouts of repair. The programs that control the cell cycle and differentiation are coordinated to ensure the correct balance of stem cells and differentiated cells in regenerating tissue, but the mechanisms that direct cells into reversible vs. irreversible arrest are poorly understood.
