Assistant Professor, Radiation Oncology
Dr. Watchman earned his undergraduate degree in physics and exercise physiology at Brigham Young University. He received a graduate degree in health physics at Idaho State University, and a doctorate in medical physics at University of Florida. Prior to his appointment as assistant professor at the University of Arizona Cancer Center, Dr. Watchman completed residency training in radiation oncology physics at the University of Arizona in 2007. He is an American Board of Radiology certified medical physicist.
Dr. Watchman is involved in image guided therapy research. Additionally, he is interested in multi-modality imaging methods for the assessment of treatment efficacy, molecular radiotherapy, radiation dosimetry and target localization. Dr. Watchman's current research interests include radiation induced pneumonitis for patients with lung tumors, where models are utilized to evaluate how margin size and location may effect pneumonitis induction during radiation therapy, investigation of dosimetry models for use in skeletal dosimetry, primarily alpha emitter dosimetry models, stem cell localization in bone marrow, pediatric dose models, and use of TomoTherapy in the treatment of cancer.
Dr. Watchman is the graduate program director of the joint Physics and Radiation Oncology Professional Science Master’s Degree program in Medical Physics. In this role he is actively involved in the teaching of graduate students from multiple disciplines at the University of Arizona. He teaches courses in radiation dosimetry, health physics, radiation therapy and clinical medical physics. He is an active member of the Radiation Oncology Medical Physics Residency program and is currently the head of the admissions committee.
