    Research Areas
    • Pediatric obstructive sleep apnea
    • Craniofacial imaging
    • Dentofacial orthopedics 
    • Altered growth and development

    I am a dental specialist in orthodontics and dentofacial orthopedics interested in clinical research. My research efforts are focused on how the form and function of the face and upper airway are related to growth and development and obstructive sleep apnea disease in children and adolescents. The long-term goal of this work is to better understand why some children develop breathing problems during sleep and to develop effective non-invasive methods of treatment. 

    Together with an interdisciplinary team of clinicians I am currently investigating the effects of how correcting the shape and position of the jaws can help improve the quality of life and health outcomes of children with obstructive sleep apnea.   

    Current Projects

    Ongoing projects include:

    • Maxillary expansion for the treatment of pediatric obstructive sleep apnea
    • Prevalence of altered craniofacial form in children with sleep disordered breathing
    • Impact of orthodontic treatment on the upper airway volume
