Paymon Rezaii, BSc
Medical Student


Paymon was born and raised in the San Francisco Bay Area, before heading to Los Angeles for his undergraduate studies. At UCLA, he received his Bachelor’s and Master’s degrees in Bioengineering, with a concentration in Neuroengineering. Paymon then moved back to the Bay Area to conduct research for Stanford’s Spine Artificial Intelligence Laboratory, Neural Prosthetics Translational Laboratory (NPTL), and Radiological Sciences Laboratory (RSL). He is currently an M.D./M.B.A candidate at Tulane University School of Medicine, while continuing his research efforts for Stanford’s Spine Outcomes Laboratory. His research interests include the development and implementation of artificial intelligence methods to impact healthcare practices within neurosurgery.

Michael Jin
Medical Student


Michael Jin is a current Stanford medical student interested in leveraging big data analytics to understand and predict neurosurgical outcomes. He has co-authored manuscripts published in journals such as Neurosurgery, Journal of Neurosurgery, and The Spine Journal, while contributing several textbook chapters and conference podium presentations at national and international neurosurgery meetings. His hobbies include hiking, traveling, and photography, and he derives his motivation from all his mentors at Stanford Neurosurgery as well as the all the patients he has the privilege to interact with and their stories.
