Biography

Dr. Pablo A. Celnik is an associate professor of physical medicine and rehabilitation, neurology and neuroscience at the Johns Hopkins University School of Medicine. Dr. Celnik’s areas of clinical expertise include neurologic rehabilitation, stroke and traumatic brain injury.

He serves as vice chair for research in the department of physical medicine and rehabilitation, medical director of the outpatient neurorehabilitation program, and director of the Human Brain Physiology and Stimulation Laboratory at the Johns Hopkins School of Medicine.

Dr. Celnik received his medical degree from the University of Buenos Aires School of Medicine. He completed residency training in neurology in Argentina, followed by a fellowship in neurological rehabilitation at the University of Maryland and a research fellowship in the lab of Dr. Mark Hallett at the NINDS, NIH. After that, he entered the PM&R residency program at Johns Hopkins, where he was ultimately appointed chief resident. Subsequently, he was awarded a K12 Award under the mentorship of Dr. L.G. Cohen at the NIH. In 2003, he joined the Johns Hopkins faculty in the PM&R and neurology departments.

His research has focused on understanding the mechanisms underlying motor learning and motor recovery after brain lesions, and on developing new strategies to enhance motor recovery after stroke. In this area, he has published several manuscripts in highly regarded journals and books.

Dr. Celnik has received numerous prestigious awards. In particular, he received in 2010 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. In addition, he was awarded the 2010 Outstanding Neurorehabilitation Clinician Scientist Award from the American Society of Neurorehabilitation, the Clinician Scientist Award from The Johns Hopkins University, the 2006 Dennis W. Jahnigen Career Development Scholars Award from the American Geriatric Society and the Young Academician Award from the Association of Academic Physiatrists for outstanding academic performance.

Dr. Celnik is an associate editor of the American Journal of Physical Medicine and Rehabilitation. In addition, he is actively involved in the Association of Academic Physiatrist serving in the Advisory Board of the Rehabilitation Medicine Training Program (RMSTP) and the Program Committee.

    Research Summary

    Dr. Celnik’s research focuses on understanding the mechanisms underlying motor learning and motor recovery after brain lesions. The aim is 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, he has published several manuscripts in highly regarded peer-reviewed journals, as well as chapters in prominent books.

    For his research, he was awarded the 2009 Presidential Early Career Award for Scientists and Engineers (PECASE) for his research on the underlying mechanisms of “plasticity” in the brain and central nervous system, work designed to speed the development of new treatments that promote recovery of function following an injury.

    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.
