Overview
Mechanical Engineer and Neuroscientist dedicated to advancing neural engineering solutions for pressing health challenges. With a Ph.D. in Mechanical Engineering from The Pennsylvania State University, my expertise lies in the modeling and stimulation of brain tissue and the development of next-gen neural prosthetics and control algorithms for therapeutic nervous system interventions. At Massachusetts General Hospital and Harvard Medical School, I’ve delved deep into the mechanisms of micro-magnetic stimulation, designing optimized micro-coil geometries for neuromodulation and evaluating implantable device safety. My multidisciplinary collaborations span from controlling neonatal sepsis in Africa to pioneering control strategies for migraine attacks and prosthetic neuromodulation. I’m committed to continuing research that bridges mechanical engineering and neuroscience, fostering academic partnerships, and mentoring the next generation of scientists.
