Assistant Professor in Radiation Oncology.

The cancers I treat include but are not limited to breast, gynecologic, head, neck, and skin cancers. I was born in Pittsburgh, PA, moved to TX, OH, and finished high school in England. I attended college at Stanford where I majored in Human Biology, medical school in Chicago and completed residency and fellowship in Radiation Oncology at SUNY, Syracuse. My goal is to provide optimal care with attention to the physical and radiobiological aspects of radiation oncology as well as the human aspects involving an individual’s priorities and concerns.

Director of Medical Physics Education and Research

Having served from 1996 to 2021 as Chief of Clinical Physics at DH, Dr. Gladstone now focuses on the academic mission at DH and Dartmouth. The Medical Physics Education Program (MPEP) at Dartmouth offers CAMPEP accredited PhD degrees in Medical Physics. Dr. Gladstone is director of the MPEP and co-directs a laboratory investigating and developing the use of Cherenkov imaging to improve the quality assurance in radiation therapy treatments. The group has expanded focus in recent years and was the first in the world to demonstrate ultra-high dose rate deliveries from a modified clinical linear accelerator in order to study the FLASH effect for normal tissue sparing. Dr. Gladstone is working to extend the educational portfolio at Dartmouth by initiating a residency program for medical physicists who wish to enter the profession.

Data Scientist and Lecturer, Radiation Oncology, Geisel School of Medicine

Dr. Hunt is a machine learning engineer who believes in the power of data and AI to automate and improve our healthcare systems. He has a special interest in leveraging real-time imaging modalities (cine MRI and optical), which generate massive clinical datasets, to train deep neural networks in a self-supervised manner. He is currently applying this approach to perform fast deformable image registration and target tracking in real-time MR-guided radiation therapy. Dr. Hunt received his PhD in Bioengineering at Rice University. Upon completing his PhD, he joined the Dartmouth community as a Research Scientist at Thayer. In 2021, he joined Radiation Oncology as a Data Scientist to lead efforts in improving treatment planning and delivery workflows using AI.

Assistant Professor of Medicine and Radiation Oncology, Geisel School of Medicine at Dartmouth.

Dr. Russo self-identifies as a clinical radiation oncologist and “radiosurgeon”. His clinical practice focuses on treating thoracic, and primary and secondary central nervous system malignancies, and using radiosurgical techniques to treat various tumors requiring high-precision radiation therapy. He has worked with almost every commercially available radiosurgery platform and uses that breadth of experience when considering treatments for his patients. By training, Dr. Russo is a chemical engineer and brings the engineering mindset to his practice for a better understanding of the tradeoffs of the responsible integration of new technology into clinical practice. Research interests are focused improving care with outcomes research, and supporting clinical trial accrual to advance current treatment standards. Outside of clinical practice, Dr. Russo enjoys making sculptural objects and furniture with concrete, wood and steel, runs long- and ultralong- distances on forest and mountain trails, and uses large format film photography to capture images of the beauty and absurdity of modern life.

Radiation oncologist, Medical Director

Dr. Vernon is a radiation oncologist and serves as the medical director of the Southwestern Vermont Regional Cancer Center. His clinical interests include the treatment of lung, breast, and prostate cancers, though as a practitioner in a community cancer center setting he enjoys the challenge that comes with treating a broad range of cancers as opposed to a single focus. Though not all treatment options are feasible in smaller community clinics, he hopes to expand the modalities available to his local patients. He trained primarily in the Midwestern US, completing his MD at the Medical College of Wisconsin, followed by residency in radiation oncology at the University of Minnesota. He began practice as one of the first providers under the new affiliation between Dartmouth-Hitchcock and Southwestern Vermont Healthcare in 2013. Outside the clinic he enjoys hiking, principally in the Adirondacks, though he recently met a long-term goal of summitting Kilimanjaro. He runs marathons and enjoys travel abroad, especially in Africa and in Latin America.
