Research Interests:

Our objectives are to gain insight into the mechanisms by which cell growth is coordinated with cell fate during animal development and disease. We are particularly interested in understanding the roles and regulation of the Hippo pathway, an essential signaling pathway that directs mechanical and microenvironmental cues to control cell proliferation, apoptosis, cell movements, and cell fate. We are incorporating both directed and systems-based approaches to define how the Hippo pathway controls stem and progenitor populations in development, and understand how deregulation of Hippo pathway signals impacts the progression of diseases, such as cancer.
