Assistant Professor of Radiology and Radiological Science

Background

Dr. Guanshu Liu is an Assistant Professor in the Johns Hopkins Medicine Department of Radiology and Radiological Science, and he holds a joint appointment as an Assistant Professor with the F.M. Kirby Research Center for Functional Brain Imaging. Dr. Liu’s research focuses on the development of magnetic resonance (MR) molecular imaging techniques.

Dr. Liu received a B.S. in applied chemistry from the University of Science and Technology of China in 1998, an M.S. in photochemistry and photobiology from the Chinese Academy of Sciences in 2001, and an M.S. in analytical chemistry at the University of Missouri-Rolla in 2003. After completing his Ph.D. in biomedical engineering at Case Western Reserve University in 2008, he joined the Johns Hopkins staff as a research associate.

Research Summary

Dr. Liu’s current research projects focus on the development and applications of a novel MRI technique, chemical exchange saturation transfer (CEST). His team is currently developing a variety of nanoparticle-based CEST imaging probes with low toxicity, high sensitivity and high specificity, and exploring the biomedical applications of these new imaging probes. In addition, the team is also interested in exploring the biomedical uses of endogenous CEST contrast; one of their ongoing projects examines the use of the endogenous CEST MRI signal of bacterial organisms to detect and monitor bacterial infection in rodent models.
