Background

Dr. Pablo Celnik is director of the Johns Hopkins Department of Physical Medicine and Rehabilitation (PM&R) and physiatrist-in-chief at The Johns Hopkins Hospital. He is a professor of physical medicine and rehabilitation, neurology, and neuroscience at the Johns Hopkins University School of Medicine.

He serves as vice chair for research in the PM&R department, medical director of the outpatient neurorehabilitation program, and director of the Human Brain Physiology and Stimulation Laboratory. He is internationally-recognized for his expertise and research in neurologic rehabilitation, particularly with stroke and traumatic brain injury.

A native of Argentina, Dr. Celnik received his medical degree from the University of Buenos Aires School of Medicine. He completed his residency training in neurology in Argentina and a fellowship in neurological rehabilitation at the University of Maryland. He also earned two research fellowships in the lab of Dr. Mark Hallett, first, and Dr. Leonardo G. Cohen later on, both at the National Institute of Neurological Disorders and Stroke (NINDS), National Institutes of Health (NIH). In the year 2000, he entered the PM&R residency program at Johns Hopkins, where he was ultimately appointed chief resident. Since 2003, he has been part of the Johns Hopkins faculty in the PM&R, neurology and neuroscience departments.

Dr. Celnik has received numerous prestigious awards, including the Presidential Early Career Award for Scientists and Engineers (PECASE), the highest honor bestowed by the U.S. government on outstanding scientists and engineers beginning their independent careers.

Research & Publications

Research Summary

Dr. Celnik's research focuses on understanding the mechanisms underlying motor learning and motor recovery after brain lesions, and on developing new strategies to enhance motor recovery after stroke.

The aim of his research to use this knowledge to develop and test new interventions to enhance motor function in healthy individuals and in patients with neurological damage. In this area, has published more than 60 manuscripts in highly regarded journals and books.

Dr Celnik’s research has formed the foundational knowledge for the application of non-invasive brain stimulation techniques, like transcranial magnetic and electric stimulation, to understand recovery after brain lesions, augment motor learning and desgin novel rehabilitation training interventions.

For his research, he was awarded the 2009 Presidential Early Career Award for Scientists and Engineers (PECASE) and other awards.

Lab

The Human Brain Physiology and Stimulation Laboratory is focused on studying the mechanisms underlying motor learning and developing interventions to modulate motor function in humans. The aim is to understand how does the central nervous system control and learn to perform motor actions in healthy individuals and in patients with neurological diseases such as stroke. Using this knowledge, the ultimate goal is to develop strategies to enhance motor function in neurological patients.

To accomplish these interests, we use different forms of non-invasive brain stimulation techniques such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), as well as functional MRI and behavioral tasks.
