Our lab is integrated into the interdisciplinary traumatic brain injury clinic, Huntington’s disease clinic, frontotemporal dementia clinic, and Pi Beta Phi Rehabilitation Institute at Vanderbilt University Medical Center. These collaborative relationships with our colleagues in trauma surgery and neurology allow us to generate clinically relevant questions that may be addressed in a clinical setting.

  • Speech Kinematics and Acoustics Laboratory

    The Lab investigates speech motor control and execution. Research efforts are predominantly directed towards the identification of the articulatory mechanisms that underlie speech clarity/intelligibility changes in healthy speakers and speakers with dysarthria.

  • Vestibular Sciences Laboratory

    Principal Investigators: Gary P. Jacobson, Ph.D., Richard Roberts, Ph.D., and Daniel J. Romero, Ph.D.

    This lab focuses on investigations of vestibular physiology across the lifespan and clinical applications of diagnostics and management of vestibular system disorders. The projects have focused on hypotheses that have been generated in the balance disorders and auditory clinics. Study areas have included: identification of optimal methods to record vestibular evoked potentials, age-related changes in balance, factors that affect falls risk, normal development of the vestibulo-ocular reflex, as well as long-term changes in vestibular function following traumatic brain injury.

  • Voice Biology Lab

    Principal Investigator: Emily Kimball, Ph.D.

    The Voice Biology Lab focuses on the biological and physiological basis for vocal fold health and pathology. We are particularly interested in understanding the specific cellular and molecular mechanisms by which the vocal folds maintain their ability to vibrate freely. Along with this goal, we also seek to understand the circumstances that ultimately lead to the development of vocal fold lesions like nodules and polyps, which cause disordered voice production.
