Advisory Board:

Martin Bues scaled
Martin Bues, PhD

Dr. Martin Bues is a nationally and internationally recognized expert in the field of proton beam therapy. He transitioned into the field of Medical Physics after working in Mathematical Physics. He received his PhD in Physics from Harvard University in 1996. He first gained experience in proton beam therapy at Massachusetts General Hospital. At MD Anderson Cancer Center in Houston, Texas, he led the development effort for Proton Pencil Beam Scanning. These efforts led to the first clinical implementation of Proton Pencil Beam Scanning in the United States. Dr. Bues is currently the Lead Proton Physicist at Mayo Clinic in Arizona.

Farr
Jonathan B. Farr, PhD, DSc

Innovating advanced particle therapy systems and their application to patient care are the definitive aspects of Dr. Farr’s work. Coming from a background in physics and fast-neutron therapy, he transitioned into proton therapy at Indiana University where he led the clinical team in establishing continuous uniform proton beam scanning treatments that are widely used in the field today. He gained international experience as the chief medical physicist at the Westdeutsches Protonentherapiezentrum in Essen, Germany, where the developments included modulated beam scanning and integrating multi-modality imaging into particle therapy such as PET, CT, and MR, with the goal of improving therapy through a better understanding of dynamic patient and treatment processes. Since joining St. Jude Children’s Research Hospital in 2012 as the Chief of Radiation Physics, Dr. Farr has focused on preparing the institution for the inception of pediatric proton therapy prospective trials in their new proton therapy center.

Hanne2
Hanne Kooy, PhD

After doctoral studies in experimental High Energy Physics, an opportunity in Medical Physics at the University of Rochester started a career in radiation therapy. Radiation therapy, different from other medical disciplines, requires active participation of physicists in the direct clinical care of patients. As such, it has been an effective vessel for introducing engineering technologies. One such technology is proton beam radiation which has become an almost singular focus of Dr. Kooy’s career. Radiation therapy, as all medical disciplines, has also become fully reliant on information technology. Dr. Kooy’s interests lie in the effectively deployment of the appropriate, advanced and integrated technologies to support proton radiation therapy.

Zuofeng
Zuofeng Li, DSc

Dr. Li is responsible for the day-to-day technical operations of the UF Health Proton Therapy Institute. He is experienced in the research and clinical practices of advanced radiotherapy treatment planning and delivery techniques, Monte Carlo-based dose calculation methods, with over 100 publications. He is a Professor at the University of Florida College of Medicine, Department of Radiation Oncology. Dr. Li is a Fellow of the American Association of Physicists in Medicine.

BN BW 140923
Bernt Nordin, MBA

Bernt has 30 years of experience in commercially introducing new medical technologies for improved precision in radiotherapy. Stereotactic neurosurgery, image-guided surgery, stereotactic radiosurgery, 3D treatment planning, IMRT, proton therapy and light ions therapy are technologies he has introduced to world markets. He currently serves as chairman of Lioness Therapeutics AB in Sweden and interim VP of Lioness Light Ions. Bernt’s degree is from the Stockholm School of Economics.
