Eric R. Cosman Jr, PhD

Scientific Director

In his role as Scientific Director, Eric Cosman, Jr, conducts research on the physical and biological mechanisms of Radiofrequency (RF) in pain management, as well as their translation into clinical practice.  Among his academic publications are seminal reports on the electric and thermal effects of RF and Pulsed RF, including the discovery of Pulsed RF heat flashes and characterization of Bipolar RF heat lesion geometry.  He has been invited to speak at international pain conferences, medical schools, and prominent hospitals.  Dr. Cosman is also the chief designer of the G4 four-electrode radiofrequency generator.

Dr. Cosman received bachelors, masters, and doctoral degrees in Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT).  His doctoral research focused on the inference of neural networks in humans based on functional neuroimaging data, such as fMRI, MEG, and EEG.  His work was conducted in collaboration with the Surgical Planning Lab (SPL) and the Brigham and Women’s Hospital and with the Athinoula A. Martinos. Center for Biomedical Imaging at the Massachusetts General Hospital (MGH).
