Research Interests

The mission of the Humphreys Lab is to understand the cellular and molecular mechanisms of kidney regeneration and thereby identify new therapeutic strategies for humans suffering from kidney disease. A primary focus is on stem cell-based therapeutic approaches. We use mouse as a model system as well as human pluripotent stem cells. The work encompasses two main areas:

  1. Developing stem cell-based approaches to treat kidney disease in humans.
  2. Understanding the mechanisms of kidney repair and recovery after injury.
