Moyed Miften, PhD, DABR, Professor and Chief Physicist

Dr. Miften joined the faculty of the Department of Radiation Oncology at the University Of Colorado (CU) School Of Medicine as a Professor and Chief Physicist in October 2008. Dr. Miften received his Ph.D. in Nuclear Engineering in 1994 from the University of Michigan in Ann Arbor. Following graduation, he became a postdoctoral fellow in the Department of Radiation Oncology at the University Michigan, where he was involved in research developing advanced dose calculation algorithms for 3-D conformal radiotherapy. In April 1996, Dr. Miften joined the Department of Radiation Oncology at William Beaumont Hospital in Royal Oak, Michigan, as a Research Scientist.  Read More...​


Ms. Stuhr joined the physics staff at the University of Colorado Department of Radiation Oncology in 1996. Ms. Stuhr is a board certified medical physicists whose clinical interests include stereotactic radiation therapy, image guided radiation therapy, and high dose-rate brachytherapy. Ms. Stuhr also helps organizing and coordinating the dosimetry and physics teams. Ms. Stuhr’s primary research interest is investigating various techniques for treatment planning and delivery of stereotactic radiation therapy.



Francis Newman, Associate Professor Emeritus, MS, DABR
Mr. Newman joined the faculty at the Department of Radiation Oncology at the University Of Colorado School Of Medicine in April of 1987. He received his Master of Science in Medical Physics from the University of Colorado in 1984 and worked in private practice at the Allen Shivers Radiation Therapy center in Austin Texas until 1987 when he was asked to join the faculty in Radiation Oncology at the University of Colorado.  He subsequently received a Master of Science degree in the Department of Mathematical and Statistical Science at the University of Colorado Denver.  Read more...
