Siqi Liu, Ph.D.

• The Liu lab is broadly interested in how epithelial tissues sense and respond to injury.  Similar to pathogen infection, tissue injury is an ancient and universal insult that disrupts homeostasis. Prompt sensing and repair of the injury is essential for organismal health and survival. Her lab will combine biochemistry and mouse genetics to understand tissue repair through in-depth probing of molecular & cellular mechanisms, to better understand the associated pathologies such as cancer.
