Tingxi Wu, D.D.S., Ph.D., has joined the University of Alabama at Birmingham School of Dentistry as associate professor in the Department of Orthodontics, effective January 2026.
Prior to UAB, Wu served as assistant professor and director of Orthodontic and Craniofacial Development Research at the ADA Forsyth Institute. She previously held dual assistant professor appointments in Orthodontics and Oral Biology at the University at Buffalo School of Dental Medicine, State University of New York.
Earning her D.D.S. at the West China School of Stomatology, Sichuan University, she completed her Ph.D. and orthodontic specialty training at the University of California, Los Angeles. She currently serves as president of the IADR Orthodontic Research Group and the AADOCR Boston Section.
Wu’s research bridges basic science and clinical application. Her laboratory investigates molecular mechanisms of inter-species interactions and signal transduction during microbial biofilm formation, and how these processes shape oral health and disease. One of the current projects on microbial interactions in orthodontic patients – recently funded by an NIDCR R03 grant with Wu as principal investigator – will continue at UAB.
Clinically, Wu specializes in pediatric orthodontics, craniofacial growth modification, multidisciplinary care for craniofacial deformities, and management of orthodontic complications. She leads translational studies on how dental and orthodontic materials influence oral microbial pathogenesis and develops practical tools to prevent and manage complications such as plaque retention, white spot lesions, caries, and gingival inflammation. Several of her innovations have been licensed by dental companies.
“Dr. Wu brings a blend of scientific rigor and student-centered teaching to UAB Orthodontics,” said Chung How Kau, B.D.S., M.Sc.D., M.B.A., Ph.D., professor and chair, Department of Orthodontics. “Her work on oral microbial interactions and orthodontic complications will advance patient care, and her mentorship equips our residents and students to turn evidence into practice. We are delighted to welcome her to our faculty.”
Her work is widely published and has been recognized by the American Association of Orthodontists, the American Association of Orthodontists Foundation, and the International Orthodontics Foundation. Wu serves as principal investigator or co‑investigator on multiple grants supported by NIH and industry partners.
