The Baker Lab aims to develop and translate more effective neurostimulation-based approaches to help patients suffering from acquired brain injuries, including stroke and traumatic brain injury, as well as movement disorders. Our preclinical efforts emphasize novel targets and strategies to personalize the use of options like deep brain stimulation (DBS), with the help of a wide range of preclinical disease models. Our clinical work involves clinical research and trials dedicated to better understanding the effects of DBS-based treatment approaches and refining their application.
Both efforts combine behavioral, neurophysiological, and imaging data and involve crucial collaborations across neurosurgery, neurology, radiology, and biomedical engineering.
Dr. Baker has more than twenty years of experience in deep brain stimulation in preclinical models and clinical work. In addition to his Neurosciences associate staff role, Dr. Baker holds a secondary appointment in the Center for Neurological Restoration at Cleveland Clinic’s Neurological Institute. He serves as co-director of the Center of Excellence in Translational Therapies for Post-Stroke Rehabilitation.
Dr. Baker earned his PhD at the University of Arizona in Speech & Hearing Science. He then started at Cleveland Clinic in 2000 through a fellowship in Movement Disorders Research within the Department of Neurology.

My research interests are in the areas of neuromodulation, in particular the application of neurostimulation-based approaches for the study and treatment of neurological and psychiatric disease. I am currently involved in studies of the neurophysiology of movement disorders, the therapeutic mechanisms of deep brain stimulation (DBS), and the potential of novel DBS approaches to improve treatment efficacy and outcomes in both Parkinson’s disease and stroke. My work involves experimental and clinical trial research in humans as well as preclinical trials using non-human animal models of disease. Many of my projects involve close collaboration with other neuroscientists as well as neurosurgeons, neurologists, radiologists, and/or biomedical engineers.

We’re a multi-disciplinary team interested in developing and improving approaches to neuromodulation. Our research spans basic, preclinical and clinical work.
Our education and training programs offer hands-on experience at one of the nationʼs top hospitals. Travel, publish in high impact journals and collaborate with investigators to solve real-world biomedical research questions.
Learn MoreDr. Hod Dana partners with Drs. Ken Baker and Andre Machado to help understand neural activity behind deep brain stimulation for stroke.
First in-human trial phase one results, published in Nature Medicine, build on more than a decade of preclinical research.
In this three-year clinical study, Drs. Alberts and Baker will utilize virtual reality technology to isolate the causes of freezing of gait, a debilitating symptom of Parkinson’s disease, thanks to support from the Michael J. Fox Foundation for Parkinson’s Research.
