Norbert Pelc

Norbert's primary research interests are in the physics, engineering, and mathematics of diagnostic imaging and the development of applications of this imaging technology. His current work focuses on computed tomography, specifically in methods to improve the information content and image quality and to reduce the radiation dose from these examinations. He holds doctorate and master's degrees in Medical Radiological Physics from Harvard University and a BS from the University of Wisconsin in Madison. He served on the first National Advisory Council of the National Institute of Biomedical Imaging and Bioengineering of the NIH. He is a member of the National Academy of Engineering and a Fellow of the American Association of Physicists in Medicine, the International Society for Magnetic Resonance in Medicine, and the American Institute of Medical and Biological Engineering.

Marlys LeSene

I am the administrator for the Pelc Lab and the Executive Assistant to Dr. Pelc. I'm also the administrator for the Training in Biomedical Imaging Instrumentation (TBI2) training grant.  I have a degree in English and also head up many of the IT initiatives in the Department of Bioengineering.

Postdoctoral Scholars

Mats Persson

I am a postdoctoral fellow in the department of Bioengineering. My research interests include reconstruction and data processing schemes for photon-counting spectral computed tomography, and simulation and modeling of photon-counting detectors. I got my Ph.D. from KTH Royal Institute of Technology, Stockholm, Sweden, where I worked on developing a photon-counting silicon strip detector for clinical computed tomography scanners. I have also co-founded a start-up company, Prismatic Sensors, as a spin-off from my Ph.D. research. When I am not working, I like to read, take a walk or go cross-country skiing.

Graduate Students

Paurakh Rajbhandary

I am a graduate student in Electrical Engineering. I attended Trinity University in San Antonio for my undergraduate degree in Engineering Science and Physics. My research focus is on spectral imaging in X-ray technologies. I enjoy hiking and playing tennis in my free time.

Picha Shunhavanich

I am a graduate student in Bioengineering Department.  My research focus is on techniques to address challenges to photon counting detectors, including a dynamic bowtie filter, a compression algorithm for projection data, and a pulse pileup modeling.  I am from Thailand, and I completed my undergraduate studies in Computer Engineering there at Chulalongkorn University.  In my free time, I enjoy reading novels, singing, and dancing.

Sarah Divel

I am a graduate student in Electrical Engineering conducting research on the validation and optimization of CT Perfusion scans for stroke assessment. I am originally from Bethesda, MD and I graduated from the University of Notre Dame in 2014. When I am not in class or doing research, you can find me running, reading, or exploring the Bay Area.
