Geoff Nelson

Geoff Nelson, PhD, is an Associate Professor in the Department of Radiation Oncology at the University of Utah, specializing in imaging, automation, and brachytherapy. He holds dual certification in Therapeutic Medical Physics from the American Board of Radiology.

• BS: Biomedical Physics, California State University Fresno
• MS & PhD: Bioengineering, Stanford University
• Clinical Residency: Medical Physics, University of Wisconsin-Madison (2015)

His research integrates advanced imaging technologies with automated treatment workflows to enhance precision in radiation therapy. Key areas include brachytherapy optimization, real-time image guidance, and dosimetric modeling for complex anatomical sites.

Recent publications highlight innovations in Halcyon/Hypersight CBCT systems, Acuros algorithm validation for extended distance TBI, and clinical analyses of radiation-induced toxicities. Collaborative work spans pediatric cancer survivorship, prostate RT outcomes, and adaptive proton therapy frameworks.

Currently, Dr. Nelson contributes to the medical physics team at Huntsman Cancer Institute, advancing technologies like diode transmission detectors, Calypso tumor tracking, and Failure Mode Effect Analysis (FMEA) for treatment safety.
