Perry Johnson, PhD

Director of Physics

Dr. Perry Johnson is an Associate Professor in the Department of Radiation Oncology at the University of Florida, and the Director of Physics at the UF Health Proton Therapy Institute. As Director, he ensures safe, high-quality radiation therapy is delivered to each patient through a continuous focus on quality assurance and ensures UFHPTI is at the forefront of modern proton therapy practice. Dr. Johnson is a proud alumnus, returning to the University of Florida after completing residency training at the MD Anderson Cancer Center Orlando and spending several years as an Assistant Professor in the Department of Radiation Oncology at the University of Miami.

Dr. Johnson’s scholarly work includes more than 30 peer-reviewed articles, one book chapter, two pending patents, and several abstracts. He is a Principal Investigator or Co-Investigator for multiple grants and clinical trials, totaling more than $13,000,000 in award support. He serves as an Associate Editor for the International Journal of Particle Therapy and provides reviews for several other journals and conferences.

A primary focus for Dr. Johnson is patient safety. He serves as Co-Chair of the Quality and Safety Committee at UFHPTI and Chair of the American Association for Physicist in Medicine (AAPM) Work Group on the Prevention of Errors in Radiation Oncology. Through his committee work, he has led and participated in several national initiatives related to patient safety, focusing on training, education, and prospective risk analysis. He has been invited to speak on these topics at a variety of local, national, and international meetings.

Dr. Johnson is also passionate about education and teaches/advises graduate students, as well as being actively involved in training both medical and physics residents. In 2022, he was a finalist for AAPM’s Arthur Boyer Award for Innovation in Medical Physics Education and received the Medical Physics Education Award for the Department of Radiation Oncology – Jacksonville. He previously received the Exemplary Teacher’s Award, recognizing him as a top educator within the UF College of Medicine.

Dr. Johnson is board certified by the American Board of Radiology in Therapeutic Medical Physics and is licensed by the state of Florida in Therapeutic Radiological Physics. He currently serves as president-elect for the Florida Chapter of the AAPM.

What does your work at UF Health Proton Therapy Institute mean to you?

“As a graduate of the UF medical physics program, it's tremendously rewarding to return to my alma mater, where I have the opportunity to collaborate with former teachers and mentors while serving in a similar capacity for the next generation of students and trainees. UFHPTI was just coming online when I started graduate school and I remember seeing photos of the gantries and beam line and being awed by the sheer scale of it all. Serving now as Director of Physics, I appreciate even more the people it takes to operate such a facility, their professionalism, expertise, commitment, and compassion, all working to provide the best outcomes for our patients.”
