Education and Training

I received my PhD degree of Physics from Florida State University in 2006. I then pursued postdoctoral training in the Department of Radiation Oncology, at Duke University Medical Center, Durham, NC. I then joined the Faculty at the University of Nebraska Medical Center, Omaha, NE. In 2012 I came to the University of Maryland where I am currently an Assistant Professor in Radiation Oncology.

Biosketch

My research interests are in the areas of clinical data mining. With existing clinical database (patient data, radiation dose, and clinical outcomes), the treatment outcomes can be modeled and used to guide the treatment of future patients. I have devoted my efforts to model normal tissue complication probability (NTCP) using machine learning method. My clinical interests focus on development and implementation of innovative technologies in the clinical practice. While at the University of Maryland, I have implemented two programs into clinical practice: RayStation Treatment Planning System and thermal therapy program. I have contributed to non-measurement-based IMRT QA program, and TG-71 based electron dosimetry upgrade.      

I am a member of American Association of Physicists in Medicine, and American Society for Therapeutic Radiology and Oncology. I am a member of the Board of Editors for Journal of Applied Clinical Medical Physics. 

Research/Clinical Keywords
