Jonathon Van Schelt

Jonathon Van Schelt, PhD, serves as an Assistant Professor in the Department of Radiation Oncology at Rush Medical College, Rush University, Chicago. His primary academic appointment bridges clinical radiation oncology and medical physics research within Rush University Medical Center's academic medical ecosystem.

Dr. Van Schelt's research trajectory reveals two distinct phases: early-career contributions to nuclear physics and current focus on medical physics applications. His foundational work centered on precision mass spectrometry and beta decay studies using advanced facilities like the Canadian Penning Trap and CARIBU at Argonne National Laboratory. Current research emphasizes:

• Radiation dosimetry for electron therapy, stereotactic radiosurgery, and brachytherapy
• Small-field radiotherapy commissioning and quality assurance
• Cost-effective IMRT solutions for low- and middle-income countries
• Prostate motion management during SBRT using CBCT imaging
• Orthovoltage small-animal irradiation systems for preclinical research

Analysis of his 15 most recent publications (2013-2022) shows a definitive pivot from nuclear physics (pre-2016) to radiation oncology applications. The medical physics work consistently addresses clinical dosimetry challenges while innovating for global radiotherapy access, particularly through ring-based compensator systems for resource-limited settings. Earlier nuclear physics publications contributed to r-process nucleosynthesis models through precision mass measurements of exotic nuclei.
