The Laboratory of Applied Swallowing Research (LASR) at Texas Christian University (TCU) supports graduate and undergraduate student learning and research in the area of swallowing. The lab is a part of the Davis School of Communication Sciences and Disorders based out of the Miller Speech and Hearing Clinic at TCU.

The LSAR lab is directed by Dr. Teresa Drulia. Other faculty and students involved in the LASR lab research team include:

  • Laurel Lynch, MS CCC-SLP
  • Emily Dickson, BS Research Assistant
  • Aaron Garza, BS Research Assistant
  • Olivia Rush, BA Research Assistant

LASR also has between 4-6 undergraduate students volunteering in the laboratory. This provides undergraduate students opportunities to learn about or conduct research.

If you are a student interested in learning more about swallowing research, please feel free to reach out to Dr. Teresa Drulia to discuss opportunities in LASR at or 817-257-6887.


LASR aims to contribute foundational knowledge in swallowing that translates into clinical practice to improve patient outcomes.


LASR investigates mechanisms of healthy swallowing and impaired physiology of swallowing, clinically known as dysphagia.

Our specific areas of research include:

  • Coordination of breathing and swallowing in respiratory disease, such as chronic obstructive pulmonary disease (COPD)
  • Sensorimotor swallowing changes in aging and disease
  • Dosing and efficacy of swallowing treatment

This lab is fully equipped with instrumentation to analyze swallowing efficiency and coordination.

LASR faculty provide classroom instruction in evidence-based evaluation and treatment of individuals experiencing difficulty with swallowing. Our faculty provide hands-on learning opportunities for students to enhance their classroom instruction, such as fiberoptic endoscopic evaluation of swallowing (FEES) and manometry.
