Personal profile

Research Interests

Professor Petersen's lab studies the molecular and cellular mechanisms that underlie animal regeneration. Tissue repair processes are likely ancient, and this ability is highly exaggerated in flatworm planarians, which use adult pluripotent stem cells to regenerate a complex anatomy after any injury, even decapitation. Current work uses this model system for identifying components of spatial control systems that link tissue injury to regulation of identity and extent of regenerative outgrowths.
