Faculty Appointments


Dr. Yeo is a certified physicist by American Board of Radiology in Therapeutic Physics. He is patient-care oriented in his clinical physics work as well as research. He is interested in new technique implementation as well as research that has clinical impact.

Professional Background

Dr. Yeo has received doctoral training in the areas of medical physics and nuclear engineering at Georgia Institute of Technology, Atlanta, GA. He received postdoctoral training at St. Jude Children's hospital, Memphis, Tennessee.

Dr. Yeo has worked in various hospitals including Samsung Medical Center in Korea as a chief of physics, Princess Margaret Hospital in Toronto as a service leader, Cooper University Hospital, and Loma Linda Proton Center.


Dr. Yeo has developed a method of inverse dose reconstruction and applied it into three- and four-dimensional dose reconstruction. The latter topic attempts to address a very challenging issue of validating dynamic dose delivery to a moving tumor, and providing a basis for adaptive therapy of the tumor. Given the current trend of radiation therapy of lung (hypo-fractionation), this research is valuable and has significant impact in assuring the radiation delivery to a lung tumor and offering adaptive therapy to areas of potential under- and over-dose.

Dr. Yeo has contributed to a study on "Intensity modulated radiation therapy for the treatment of cervical cancer who is not suitable for brachytherapy", which led to clinical implementation as the first of its kind. He has also studied on the verification of intensity modulated therapy by film dosimetry and have written a text book which provided a guide for film dosimetry of intensity modulated therapy.
