I am a professor and the Chief of the Division of Medical Physics for the Department of Radiation Oncology at Loyola University Medical Center. I have written over 100 peer-reviewed journal articles, co-edited two textbooks related to IMRT and IGRT, and am an NIH-funded investigator. My current research interests include advanced imaging techniques, motion tracking, and adaptive radiotherapy.


Education
  • Bachelor's degree, De Paul University
  • Master's degree, De Paul University
  • PhD, University of Chicago

What prompted you to pursue your field?

When I was in college, I learned about the field of medical physics from a fellow student. He would describe how he was going to the radiation oncology clinic, and all of the physics that was involved in treating patients. I was fascinated that one could use the principles of physics to help patients in their time of need and decided this was the career I wanted to pursue.

What would you tell a student about why your field is exciting or important?

Medical Physics is an exciting field with technology that is ever-evolving to better diagnose and treat patients. However, well-trained medical physicists are needed to ensure this technology is being used optimally. There is a satisfaction knowing that the daily work of a medical physicist improves the lives of countless patients.

What called you to or attracted you to Loyola?

Loyola is a great place with a strong sense of community and with people who have a willingness to go above and beyond what is required.
