Dr. Weaver is recognized nationally and internationally for her research on the effect of daytime sleepiness on daily behaviors and assessment of treatment outcomes. Her program of research centers on treatment adherence, analysis of treatment efficacy for obstructive sleep apnea, and mechanisms and outcomes of daytime sleepiness. She has expertise in issues related to functional status/quality of life, treatment adherence, instrument development, and randomized clinical trials.  Dr. Weaver has produced two notable disease specific functional status measures, one for chronic pulmonary disorders and the other for sleep disorders. The latter, the Functional Outcomes of Sleep Questionnaire has become the gold standard for the evaluation of the impact of impact of treatments for sleep disorders to improve quality of life, which has been translated into 51 languages and used internationally in clinical trials.  Her program of research centers on treatment adherence, analysis of treatment efficacy for obstructive sleep apnea, and mechanisms and outcomes of daytime sleepiness. Extending outcomes beyond physiological measures, Dr. Weaver has conducted multisite research to determine the appropriate duration of nasal continuous positive pressure treatment for obstructive sleep apnea required to normalize key behaviors such as functional status. Dr. Weaver and colleagues were the first to characterize the acute decline in adherence observed over the first week of nasal continuous positive airway pressure treatment for obstructive sleep apnea. This work was extended in a study designed to isolate factors contributing to this non-adherence, in which Dr. Weaver serves as the Principal Investigator. She also was the first to describe the dose-response relationship between hourly duration of CPAP use and normalization of salient clinical outcomes.  This research was the basis for the AASM recommendation that adherence to CPAP treatment be objectively monitored and use of this therapy should be monitored with appropriate intervention in the first week of treatment.  Dr. Weaver has completed the first and largest multisite randomized clinical trial evaluating the effectiveness of nasal continuous position airway pressure for milder sleep apnea.  Dr. Weaver’s research has been supported by the National Heart Blood and Lung Institute of the National Institutes of Health. In 2018, she was selected to join the first class of fellows of the American Thoracic Society.
