Biography

Soonmee Cha, MD, is a Professor In Residence of Radiology and Neurological Surgery at the University of California, San Francisco. She is the Diagnostic Radiology Residency Program Director, and she is Radiology's Vice-Chair of Education. Dr. Cha has focused on the importance of validating the usefulness of MRI as a tool for brain tumor diagnosis, monitoring and identifying therapy endpoints. She obtained her medical degree from Georgetown University, School of Medicine, Washington in 1991. She completed her Diagnostic Radiology residency from North Shore University Hospital, Cornell University Medical College in New York, followed by a fellowship in Neuroradiology from New York University Medical Center in 1998.

Dr. Cha is committed to a career dedicated to patient-oriented research in the field of brain tumor imaging. She believes that non-invasive imaging technology will make important contributions to the health of patients through improving the specificity and precision of diagnosis and treatment monitoring, which will have significant impact on therapeutic decisions.

The main focus of Dr. Cha’s research is to identify reliable surrogate markers of prognosis and therapeutic efficacy by quantitative MR imaging methods in patients with brain tumors. She believes that by using MR imaging techniques such perfusion MR imaging, diffusion-weighted imaging, and 3-dimensional proton magnetic resonance spectroscopic imaging, detection of changes in tumor angiogenesis, cellularity, invasion, tumor hypoxia, and metabolic burden can be accurately measured and will provide more specific information about patient’s early response to therapy in the context of tumor growth.

Dr. Cha has been awarded several NIH grants, serving as Principal Investigator and Co-Principal Investigator on many NIH projects. She has published 87 articles, and she has written 77 peer-reviewed articles and 4 book chapters.
