Machado, Andre, MD, PhD

Machado webResearch Statement

Dr. Machado leads several deep brain stimulation and neuromodulation clinical trials as well as laboratory research. His research in deep brain stimulation for thalamic pain syndrome was awarded the National Institutes of Health Director’s New Innovator’s Award. In addition, he conducts deep brain stimulation research for treatment refractory depression as well as obsessive compulsive disorder. His laboratory in the Lerner Research Institute is focused in developing new strategies for utilizing neuroprosthetic devices such as DBS to improve post-stroke rehabilitation. His current NIH funded research is aimed at evaluating the effects of deep cerebellar stimulation on post-stroke perilesional plasticity and recovery of function.
