Reflections and Looking Ahead – Summer 2026
As we enter the summer of 2026, this is a moment to reflect on the strengths that define our department, to recognize the individuals who have shaped its impact, and to look ahead to new opportunities developing across the Department of Medical Physics and the School of Medicine and Public Health (SMPH).
At its core, our department advances dual missions of research and education in close collaboration with clinical partners, developing innovations that improve patient care in Wisconsin and beyond while training the next generation of leaders in medical physics. This intersection of discovery, translation, and education remains a defining strength of the department.
