Arthur Petusseau

Assistant Professor of Engineering

Overview

Dr. Arthur Petusseau earned dual Master’s degrees in Engineering and Science from the University of Strasbourg, France, in 2018 before completing his PhD in Biomedical Engineering at Thayer. His research focuses on developing innovative time-gated optical imaging technologies to enhance cancer diagnostics and treatment. Dr. Petusseau specializes in creating advanced imaging systems and minimally invasive diagnostic tools, prioritizing novel methodologies over commercial solutions. With expertise in hardware development and hands-on experience in living systems biology and animal surgery, he works to translate cutting-edge lab-born technologies into clinical applications.

    Exploring the role of oxygen in ultra high dose rate radiotherapy

    Ultra-high dose rate (UHDR) radiotherapy (RT) is an emerging cancer treatment that delivers high-energy beams (>40 Gy/s) to target tumors. Unlike conventional radiotherapy, which can damage healthy tissue, UHDR RT has been shown to spare normal tissue while maintaining tumor-killing effectiveness—a phenomenon known as the FLASH effect. The underlying mechanisms of this effect remain unclear. Our research focuses on investigating the role of oxygen in the FLASH effect using optical methods to measure tissue oxygen levels in real time during treatment.
