He was previously the Associate Director of Research at the Surgical Artificial Intelligence and Innovation Laboratory at the Massachusetts General Hospital, where he continues to serve as a senior consultant and fellow in surgery at Harvard Medical School. He obtained his B.A. in Biology with a specialization in Neuroscience from Boston University. He earned his MD from the University of Pennsylvania. He also obtained an M.S. in Translational Research with a focus on technology and surgical education for which his research was conducted at the Imperial College London under the supervision of Professor the Lord Ara Darzi, Rajesh Aggarwal, and the late K. Anders Ericsson. He completed the Surgical Education Research Fellowship and the Surgical Artificial Intelligence and Innovation Fellowship at MGH and Harvard Medical School. He is the editor of the textbook Artificial Intelligence in Surgery: Understanding the Role of AI in Surgical Practice.

His research lies at the intersection between surgical data science and surgical education, exploring computer vision techniques as applied to surgical performance assessment and decision inference. His research has previously focused on investigating methods of improving the efficiency and quality of technical skills acquisition. He has published on using virtual and augmented reality to assist in the acquisition of surgical technical skills, curriculum development for surgical skills, and the utilization of wearable technology in the operating room. 

As a general surgery resident at MGH, he co-founded the MGH Surgical Artificial Intelligence and Innovation Laboratory (SAIIL) with Dr. Ozanan Meireles and is in collaboration with Professor Daniela Rus and Guy Rosman of MIT CSAIL. His research includes the use of artificial intelligence and computer vision in the operating room for surgical education and clinical decision support. He is the co-founder and former co-course director of the Harvard Surgical Program in Innovation (SPIN), which aims to educate surgeons on the innovation design process.

Dr. Hashimoto holds leadership positions in several national organizations. He is a member of the Royal College of Physicians and Surgeons of Canada Artificial Intelligence Task Force, the American College of Surgeons Academy of Master Surgeon Educators Subcommittee on AI, co-chair of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) AI Task Force, and chair of the Association for Surgical Education AI Task Force. He was a member of the Board of Directors of the Association of American Medical Colleges (AAMC) from 2016-2020 and served on the Board of Governors of SAGES (2017-2019).
