Dr. Jeffrey Palmer is a professor of physical medicine and rehabilitation (PM&R), otolaryngology-head and neck surgery, and functional anatomy and evolution at the Johns Hopkins University. He also directs the Swallowing and Oral Function Laboratory.
After initial piano studies at the Juilliard School, Dr. Palmer obtained his undergraduate and medical degrees from New York University, and completed a residency in PM&R at the University of Washington in Seattle. A member of the Johns Hopkins faculty since 1983, Dr. Palmer reached the rank of professor in 2002. From 2004-14, he served as the Lawrence Cardinal Shehan Professor and Chair of the Department of PM&R and Physiatrist-in-Chief of the Johns Hopkins Hospital. He is also a Visiting Professor at the Medical College of Wisconsin and at Fujita Health University in Japan.
Dr. Palmer is internationally known for his research on swallowing and its disorders, which was supported by the National Institutes of Health for more than 20 years. His research currently focuses on neural control of mastication and swallowing and dynamic imaging of swallowing with videofluoroscopy and high-resolution computed tomography.
The first editor-in-chief of Current Physical Medicine and Rehabilitation Reports, Dr. Palmer also serves on the editorial advisory boards of Dysphagia and the Japanese Journal of Comprehensive Rehabilitation Sciences. He is a Past-President of the Dysphagia Research Society and held leadership roles in the Association of Academic Physiatrists. He has received numerous honors in the United States and abroad.

Research & Publications
Dr. Palmer’s laboratory focuses on understanding the kinesiology and biomechanics of swallowing, with special attention to the integration of mastication and swallowing and to the motor control of the tongue and jaw. Studies use videofluoroscopy (x-ray video), dynamic CT scanning, and measurements of muscle activity (EMG) and respiration to analyze control of eating, swallowing, and breathing in both healthy volunteers and individuals with stroke, head and neck cancer, neurological disease, and inflammatory muscle disease.
