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, Ph.D., Postdoctoral Fellow

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.

Qiong Xu, Ph.D., Postdoctoral Fellow
Email »

Qiong is working on reconstruction algorithm and data correction method for X-ray CT. This work aims to improve image quality and get more information for better diagnosis and IGRT.



Raiyan Zaman, Ph.D., Postdoctoral Fellow
Email »

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.

Morteza Mardani, Ph.D., Postdoctoral Fellow
Email »

Morteza earned his MSc in Electrical Eng. from the University of Tehran, Iran, at 2009. He then joined the University of Minnesota, twin cities, to pursue his PhD in Electrical Eng. under the supervision of Prof. Georgios B. Giannakis, where he just graduated in May 2015. As a part of the program, Morteza visited the AMP Lab and International Computer Science Institute at UC Berkeley last Spring semester. His research expertise is generally on signal processing, optimization, and machine learning, where he uses his tools for dealing with emerging data science problems in healthcare.

Don Vernekohl, Ph.D., Postdoctoral Fellow
Email »

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.




Siavash Yousefi, Ph.D., Postdoctoral Fellow

Siavash is working on cancer imaging and image-guided cancer therapy monitoring systems.







Cesare Jenkins, Ph.D. Candidate
Department of Mechanical Engineering
Email »

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
Department of Electrical Engineering
Email »

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.

Baris Ungun, M.D.-Ph.D. Candidate
School of Medicine, Department of Bioengineering
Email »

Baris Ungun is currently an M.D.-Ph.D. candidate in Bioengineering at Stanford University, working under the guidance of Professor Xing and Professor Stephen Boyd. His current research involves convex optimization in radiation therapy treatment planning.
