Research Interests

I am interested in the epidemiology of sleep disorders, particularly sleep disordered breathing and the translation of research findings to patient care and public awareness. Previous projects have been the following: Sleep Heart Health Study (Observational cohort study to determine the cardiovascular consequences of sleep-disordered breathing; Role: Steering Committee Chair and PI of the University of Arizona site), Tucson Children’s Assessment of Sleep Apnea (TuCASA, Observational cohort study to determine the impact of sleep disordered breathing in children; Role: PI), and the Applied Positive Pressure Long-term Efficacy Study (APPLES, Randomized clinical trial to determine the neurocognitive consequences of sleep disordered breathing; Role: PI University of Arizona site). Currently, I am involved in studying the impact of sleep deficiency on diabetic control in type 1 diabetes, curriculum development pertaining to sleep for elementary, high school and college students, and increasing public awareness about the detrimental impact of sleep deficiency and disorders.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
