Research interests include craniofacial biology, mesenchymal stem cell signaling, and circadian rhythm regulation in bone regeneration. Their studies integrate molecular biology with clinical dentistry to address age-related joint degeneration and periodontal phenotypes.

Article trends highlight expertise in mechanotransduction (e.g., Piezo2+ neuron interactions), spatial transcriptomics for developmental biology, and MSC-based therapies targeting circadian pathways. Notable collaborations span multiple institutions in craniofacial signaling research.

Current work includes investigating lubricin depletion in temporomandibular joint osteoarthritis. Past roles involved clinical residency in orthodontics and dental general departments at West China Hospital of Stomatology.
