Giuseppina Pilloni, PhD
Dr. Pilloni is an assistant professor in the Department of Neurology. She received her doctorate in industrial engineering from the University of Cagliari (Italy) in 2020 and completed a fellowship at NYU Grossman School of Medicine in Clinical Neuromodulation. She joined the Neuromodulation Lab sustaining her long-term interest in studying mechanisms of action and effects of noninvasive brain stimulation techniques. Dr. Pilloni previously studied the use of motor cortical stimulation combined with motor training to restore and preserve function in people with multiple sclerosis. In the Neuromodulation Lab, as a biomedical engineer, she focuses on optimizing noninvasive brain stimulation, specifically tDCS, and wearable technologies for at-home use. Her current research focus is on understanding the mechanism of action of tDCS and developing appropriate dosing parameters and biomarkers for its use in treating the symptoms of neurological diseases such as motor and cognitive impairments, fatigue, and depression. She also has extensive experience in the use of wearable and digital technologies for quantitative and objective human movement analysis and in bio-signals processing (for example, HR signal, and imaging) in a variety of patient populations. Alongside her research contributions, Dr. Pilloni is an active mentor to students and junior researchers in the lab. Outside of work, Dr. Pilloni is a former professional basketball player, and she remains an avid sports enthusiast.
