I joined Loyola in 2016 as a clinical medical physicist and as an assistant professor at the Stritch School of Medicine. My research mainly focuses on the development and evaluation of advanced reconstruction algorithms in cone-beam CT (CBCT), with an emphasis on their applications to improve CT imaging quality, reduce CT imaging dose, and optimize the design of CT imaging systems and protocols. My dissertation was awarded as the Best Dissertation by the Graduate Program in Medical Physics (GPMP) at the University of Chicago. I am very active in the field of medical imaging and have served as a reviewer for a number of medical imaging journals and several international conferences.

Research Interests

My clinical interests include CT imaging protocol optimization, dual-energy CT, breast CT, and tomosynthesis.

  • Bachelor's degree, Tsing Hua University
  • Master's degree, Purdue University
  • PhD, The University of Chicago  

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 or important?

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.
