Ryan Halter, PhD
Associate Professor, Thayer School of Engineering, Dartmouth College
Dr. Ryan Halter, Associate Professor at Dartmouth’s Thayer School of Engineering, studied Engineering Science and Mechanics and Biomedical Engineering at Pennsylvania State University and Dartmouth. He holds Adjunct faculty appointments in Dartmouth’s Computer Science Department and in the Department of Surgery at Dartmouth’s Geisel School of Medicine where he is also a member of the Cancer Imaging and Radiobiology Program at the Norris Cotton Cancer Center. He received his BS and MS from Penn State in 1999 and 2001 and his PhD from Dartmouth in 2006 for his development of an electrical impedance tomography device for breast cancer imaging. He spent the next two years at Dartmouth-Hitchcock Medical Center working on a Post-Doctoral Fellowship he was awarded from the Congressionally Directed Medical Research Program of the DoD to investigate the potential clinical applications electrical impedance sensing might have in prostate cancer detection. Based on findings from this effort, he has initiated a research program exploring and developing technologies for sensing and imaging electrical properties of tissue for clinical applications.
In addition to his work in electrical property sensing and imaging, his general research interests lie in the field of medical devices where he focuses on developing wearable tech, surgical devices, and medical imaging approaches all focused on enabling clinicians to better detect, diagnose, stage, treat, and monitor patients with a variety of pathologies. His research activities include designing devices, evaluating these devices in bench-top and ex vivo settings, and deploying these technologies in human feasibility trials. In addition to his academic research pursuits, he has a start-up company, RyTek Medical, that focuses on translating the technologies being developed in his lab to the market.
