I am designing instrumentation for high sensitivity x-ray fluorescence imaging. This imaging method acquires an x-ray signal that is specific to a nano-particle. These nano-particles are conjugated with ligands specifically targeting disease, This molecular imaging method can image the molecular markers of disease deep in tissue without using expensive radiopharmaceuticals.

Dengwang Li grew up in Shanxi, China. He received both his BS and MS from Shandong University in China. He earned his PhD degree also from Shandong University, and won a joint PhD program with the University of Sydney sponsored by CSC, in Australia. His dissertaion focused on medical image processing with application in the image guided radiation therapy. In the Xing lab he is working with Dr.Ruijiang Li and Dr. Xing Lei on the medical image processing with the applicaton on the cancer treatment.

My current research is focused on transferring ionizing radiation energy into optical signals for imaging and dosimetry. Currently I am designing a single point wide energy range optical dosimeter for EBRT and HDR modalities. I have completed studies on diagnostic x-ray induced photoelectric effect in MOFs/metal-organic frameworks, hard x-ray-induced optical luminescence and Cerenkov radiation energy transfer by gold
nanoclusters for imaging and therapy..

My research interests are focused on developing affordable biomedical optical imaging systems. Therefore, my long term objectives aim to develop optical technologies for early diagnosis using molecular markers and treatment of atherosclerotic plaque. My research emphasizes three main areas: (1) imaging mechanisms, (2) technology development, and (3) translational research. This is a collaborative effort between the Division of Radiation Physics and Cardiovascular Medicine to develop minimally invasive optical imaging technologies. My current research project focuses on the improvement of the characterization of atherosclerotic plaques within the coronary arteries, using a dual-modality intravascular molecular optical imaging system to detect glucose uptake.

Don is working on the next generation of dosimetry detectors build from diamondoid and nano-diamonds. He studied at the University of Münster and CERN where he worked on detector development and instrumentation. Beyond diamond detectors, he is interested in preclinical PET detectors based on semi-conductor and gas detectors as well as applications in high energy physics and radiation therapy.

Cesare is working on a project to develop tools to track radiation therapy in real time. The project aims to improve patient safety while providing additional treatment delivery validation information to clinicians. Additionally, he collaborates with others in the lab on the development of x-ray florescence computed tomography (XFCT), a novel molecular imaging modality


Henry Wang, Ph.D. Candidate

Henry Wang is currently a Ph.D. candidate in Electrical Engineering at Stanford University, working under the guidance of Professor Xing. His current research involves knowledge based treatment planning and optimization. He is developing a fully automated treatment planning platform. His past research includes applying cloud computing to monte carlo in radiotherapy. Working with new ideas and producing useful yet simple implementations are truly meaningful for him. He hopes to utilize his engineering background and one day make a groundbreaking contribution to medical physics.
