Our lab mission is to cultivate an inclusive, collaborative community of scientists to define mechanisms driving robust regeneration in the planarian model.

Our primary areas of research focus are: 1) investigating cellular and molecular players in brain regeneration; 2) understanding interactions between glia and neurons in the context of regeneration; and 3) discovering signals important for activation and coordination of cells—particularly stem cells—in regeneration. Our goal is to discover foundational themes and even specific pathways that might one day be leveraged to improve regenerative therapies.
