Junguo Bian
  • Junguo Bian received his PhD in Medical Physics from University of Chicago in 2012. He subsequently became a post-doctoral fellow in the Department of Radiology at the University of Chicago. In 2013, he became an instructor of Radiology at Harvard Medical School (HMS) and Mass General Hospital (MGH). He joined Loyola in 2016 as a clinical Medical Physicist and an Assistant Professor at the Stritch School of Medicine. His research mainly focuses on the development and evaluation of advanced reconstruction algorithms in cone-beam CT (CBCT), with an emphasis on their applications to improving CT imaging quality, to reducing CT imaging dose, and to optimizing the design of CT imaging systems/protocols. His dissertation was awarded as the Best Dissertation by the Graduate Program in Medical Physics (GPMP) at the University of Chicago. He is very active in the field of medical imaging and has served as a reviewer for a number of medical imaging journals and several international conferences. His clinical interests include CT imaging protocol optimization, dual-energy CT, breast CT, and tomosynthesis.

    What prompted you to pursue your field?

    When I was in graduate school, one of my college classmates introduced me to the Medical Physics program. I realized that this is such a fascinating field and decided to pursue a career in Medical Physics.

    What would you tell a student about why your field is exciting/important/the potential impact s/he could make?

    Medical Physics mainly includes medical imaging (Radiology) and cancer treatment (Radiation Oncology). It is a very interdisciplinary field of applied physics and represents the cutting edge of medical instruments.

    What "called" you to/attracted you to Loyola?

    Loyola is great place, and I am glad to be a member of the community.
