Dr. Chai’s laboratory is interested in early craniofacial development and malformations, including the molecular regulation of cranial neural crest cells. His laboratory has developed genetically engineered mouse models, and has made important discoveries about the mesenchymal stem cell (MSC) niche in the craniofacial region and about utilizing MSCs with 3D printed scaffolds for tissue regeneration.
