About This Lab

This multidisciplinary research laboratory studies the interrelated mechanisms of swallowing, breathing, ingestion, airway clearance, airway compromise and movement of materials throughout the upper aerodigestive system.

Specifically we are working to :

  1. Delineate mechanisms contributing to upper aerodigestive regulation and dysfunction as a preclinical indicator of disease across the lifespan.

2. Developing and testing of novel biomarkers as research tools for prehabilitation and rehabilitation studies.

3. Applying and evaluating novel therapeutic options for the rehabilitation of upper aerodigestive disorders.

SwallowFit Officially Announced by UT Health

UT Health officially announced the SwallowFit Study! The randomized double-blind clinical trial plans to enroll about 80 participants to test a novel treatment program designed to strengthen and retrain swallowing function in people with early Parkinson’s. Participants will include current and former military service members and direct relatives who are between the ages of 30 […]
