Research summary: My research interest is to develop cutting-edge biomedical technologies that bridge the basic physics/engineering research and pre- and clinical cancer therapy application. The main focus of my group is to advance optical imaging for soft tissue target localization and response assessment in preclinical radiation research. My research work is supported by the mechanism of Academia Industry Partnership (AIP) from NIH and industrial grants. My colleague and I have successfully integrated the cone-beam CT (CBCT) and bioluminescence tomography (BLT) to guide focal irradiation with the small animal radiation research platform (SARRP). Our work has led to Xstrahl’s, our industrial partner, commercialize the optical utility for the SARRP. To further bring the SARRP targeting and functional imaging capability to the next level, we will incorporate quantitative BLT and fluorescence tomography (FT). We believe that the tri-modal imaging system (CBCT/BLT/FT) will greatly expand the capabilities for pre-clinical radiation research that has not been the focus of the molecular optical imaging industry at large.
In addition to the biomedical optics, my research background spans a broad range of topics that cover photodynamic therapy (PDT), beam data modeling and quality assurance for radiation therapy, prostate motion management techniques and condensed matter physics.
