      Youngho Seo, PhD, is an Associate Professor in Residence and Director of Nuclear Imaging Physics in the Department of Radiology and Biomedical Imaging, Associate Professor in Residence in the Department of Radiation Oncology at the University of California, San Francisco, and Physicist Faculty Scientist at Lawrence Berkeley National Laboratory. He received his bachelor's degree in Physics from Korea Advanced Institute of Science and Technology (KAIST). He completed two master's degrees in Physics at the University of Alabama in Huntsville, and at the University of California, Los Angeles (UCLA). Dr. Seo completed his PhD in Physics from UCLA under the supervision of Professor David Cline, followed by postdoctoral training at the same institution. He joined the UCSF Physics Research Laboratory in 2003, and was trained under the supervision of Professor Bruce Hasegawa before joining the faculty in 2006.

      Dr. Seo leads a group of physicists and engineers working in the field of radionuclide and x-ray imaging instrumentation and physics, and directs the UCSF Physics Research Laboratory (PRL). His primary research focus is to use quantitative SPECT/CT, PET/CT, and PET/MR molecular imaging for a broad range of research areas from small animal imaging using dedicated animal imaging systems and basic instrumentation development to physics analysis of clinical research data. Visit the UCSF PRL webpage to learn more about the current projects.

      Dr. Seo also directs the preclinical PET/SPECT/CT/Optical imaging core facility at the UCSF Center for Molecular and Functional Imaging at China Basin. If you are interested in using this core facility, or establishing a collaboration, please visit the core webpage, or contact Dr. Seo.
