Richard D. Andreatta, Ph.D.

Associate Professor
Division of Communication Sciences & Disorders Department of Rehabilitation Sciences

Richard D. Andreatta is an Associate Professor in the Division of Communication Sciences & Disorders within the Department of Rehabilitation Sciences. He is also a faculty associate in the Spinal Cord and Brain Injury Research Center (SCoBIRC) at the UK College of Medicine. Dr. Andreatta received his Ph.D. in Speech Physiology and Neuroscience in 1999 from Indiana University, Bloomington. At the University of Kentucky, Dr. Andreatta is the director of the Laryngeal & Speech Dynamics Lab. This shared facility contains several specialized hardware and software systems for testing, recording and analyzing orofacial sensory perception, orofacial muscle force, vocal tract aerodynamics, and trigemino-facial brainstem-level evoked reflexes. Other capabilities of the LSD lab include stroboscopic laryngeal imaging (ridged and flex-scoping), EGG, and acoustic analyses of speech.

Scholarly Interests

Dr. Andreatta is currently active in three research areas encompassing different aspects of vocal tract physiology and behavior in both animal and human models. Interdisciplinary collaborations with colleagues in the Departments of Physiology, and Behavioral Science (College of Medicine) and the Athletic Training and Physical Therapy programs in the Department of Rehabilitation Sciences (College of Health Sciences), have been instrumental in the development of these research areas:

Laryngeal Anatomy & Muscle Physiology

NIH-funded project (co-investigator) to define the responsiveness of laryngeal muscle to re-organize under fictive endurance training conditions in aging rodent models. Related work includes studies using growth factors to improve laryngeal muscle function in aging animal models and anatomical investigations of the mouse laryngeal complex.

Brain Imaging Studies of Human Vocalization

In human populations, Dr. Andreatta is pursuing several studies using functional magnetic resonance imaging (fMRI) to investigate neural biomarkers of laryngeal control during speech production under normal and perturbed performance conditions.

Orofacial Sensory Physiology

Current studies are investigating the orofacial sensory detection capacities of both healthy young and aging individuals under orofacial low-level force control task conditions.

Educational Focus

Dr. Andreatta teaches undergraduate courses in the Communication Sciences & Disorders program including: CD 378 – Anatomy & Physiology of Speech, CD 402 – Speech Sciences, and CD 571 – Neural Bases of Speech & Language. He also teaches and mentors doctoral-level students in courses such as RHB 710 – Neuroplasticity in Rehabilitation Sciences, and in a variety of independent study experiences within the topical areas of communication neuroscience, sensorimotor integration, speech sensorimotor control, dynamic systems theory and network models of brain function.
