Sumientra Rampersad is an Assistant Professor of Physics at UMass Boston and a Visiting Assistant Research Professor of Physical Therapy, Movement and Rehabilitation Sciences at Northeastern University. Sumientra received her Bachelor’s and Master’s degrees in Natural Sciences from the Radboud University in Nijmegen, the Netherlands, completing research theses at the departments of Applied Physics, Biophysical Chemistry, and Medical and Biophysics. After a period of teaching English in Central America, she returned to Nijmegen to pursue a PhD in Medical Science at the Radboud University Nijmegen Medical Centre under the guidance of Prof. Dick Stegeman and Dr. Thom Oostendorp. After working on simulations for a biomedical company, Sumientra started a postdoctoral position at Northeastern University’s Center for SPIRAL, under the guidance of Profs. Deniz Erdogmus and Dana Brooks. In 2019, she established the Brain Stimulation & Simulation lab as a Research Assistant Professor at Northeastern. In 2021, Sumientra started a tenure-track position at UMass Boston, where she continues to pursue brain stimulation research through computational modeling and human experiments. Additionally, she teaches PHYSIC 610: Special Topics in Medical Imaging, and PHYSIC 114: Fundamentals of Physics II. In 2023, Sumientra received an NIH R01 grant to investigate temporal interference stimulation, which has become one of her main research interests.
