Philip, Benjamin A., PhD

Clinical Interests 

Dr. Philip's areas of interest include motor skill learning, functional rehabilitation and compensation after unilateral hand impairment, and how hand dominance interacts with function and rehabilitation.

Research Interests

Dr. Philip directs the Neuroscience and Rehabilitation Laboratory, which focuses on the interaction between hand dominance, brain lateralization, and rehabilitation and compensation following unilateral impairment such as stroke, amputation, or nerve injury. He combines behavioral, neuroimaging, and neuro-stimulation methods to understand how the brain and body change after impairment, and how they can further change during rehabilitation. Toward this end, he is also interested in the cortical asymmetries that underlie handedness and hand-specific learning. By understanding the cortical asymmetries that drive activities of daily living, and how this organization changes in pathological conditions, he hopes to improve rehabilitation and quality of life for patients with unilateral impairment, especially of the dominant hand.

Teaching Roles

Dr. Philip co-teaches the Neuroscience Principles of Performance courses, and lectures on theories of the brain and motor control for Theory and Foundations for OT Practice. In addition, he mentors MSOT and OTD students who work in his laboratory.

Education

2009: PhD in neuroscience, Brown University
2002: BA in cognitive science (with correlate sequence in Biology), Vassar College

Background

Dr. Philip began his scientific career in the lab of John Donoghue at Brown University, where he implanted electrode arrays into the motor cortex of non-human primates to study the cortical control of movement. His dissertation work identified how cortical areas interact differently when performing continuous feedback-driven movements, as opposed to simple ballistic linear movements. In 2009, Dr. Philip moved into human research when he joined Dr. Scott Frey at the University of Oregon as a postdoctoral fellow. Over the following five years, Dr. Philip followed Dr. Frey to the University of Missouri and Washington University to continue their collaboration and investigate how amputees' brain and behavior change after their injuries, and how these changes can alter anew after restoration of the hand via transplant or replant. He started the Neuroscience and Rehabilitation Laboratory in 2016. Dr. Philip is a member of the Society for Neuroscience, Neural Control of Movement Society, American Congress of Rehabilitation Medicine and American Society for Neurorehabilitation.
