Research Interests

Dr. Custis is a member of the veterinary radiation oncology team at the Colorado State University Animal Cancer Center. His research interests center upon evaluating the response of spontaneously occurring tumors to ionizing radiation. Utilization of the latest technology, allows for the precise delivery of intensity modulated radiation therapy (IMRT) and stereotactic radiation therapy (SRT) plans, novel to veterinary medicine. Both modalities seek to maximize local tumor control, while minimizing the impact upon surrounding normal tissues. His efforts, to date, are focused upon the ongoing clinical study of stereotactic radiation therapy both as a limb sparing option for canine appendicular osteosarcoma and as novel treatment for canine nasal tumors.
