Pin-Xian Xu’s laboratory studies regulatory networks that drive organogenesis. In particular, our lab is interested in the general question of how cell diversity in our body is created. A major focus of our research is auditory and renal development and maintenance, where we seek to identify the pathways by which EYA1 drives a small group of progenitor cells to become functional sensory neurons and hair cells in the inner ear or nephrons in the kidney.
