Dr. Cammin received his Ph.D. in experimental particle physics from the University of Bonn in Germany in 2004. He continued to study the fundamental particles and forces as a postdoctoral researcher using high-energy particle accelerators at Fermilab (Batavia, IL) and at CERN (Switzerland). Dr. Cammin transitioned to the field of medical physics in 2009 when he joined the Johns Hopkins University in Baltimore. His research focused on CT image reconstruction and novel detectors for computed tomography. In 2015 he obtained a Certificate in Medical Physics from the University of Pennsylvania in Philadelphia. Dr. Cammin completed his residency in therapeutic medical physics at Washington University / Barnes-Jewish Hospital in St. Louis in 2017 where he then worked as a clinical medical physicist and faculty member. Dr. Cammin joined the Department of Radiation Oncology at the University of Maryland Medical Center in 2020 as an Assistant Professor.
