Educational Background:
Areas of Research Interest: Magnetic Resonance Imaging and Spectroscopy My research activities mainly focus on magnetic resonance imaging (MRI) and spectroscopy, especially their clinical applications. The first area of interest is to investigate novel or improved MR imaging strategies for the assessment of human tumors in breast, prostate, etc. In addition to the efforts to enhance image quality, I am also interested in developing automated image processing and analysis methods to extract the information needed such as volume change and biomarker response. These image processing and analysis methods may include image artifact removal, image segmentation, image coregistration, and customized automated quantification. Further research efforts will focus more on real-time imaging and processing for the applications such as in image guided intervention and image guided therapy.

In addition to these various research endeavors, I am supporting clinical and research needs in MRI at the University Hospital. I also teach "Introduction to Magnetic Resonance Imaging Physics" for graduate students in the Radiological Science Program at UTHSCSA.
