Christopher Nguyen, PhD

Research Scientist Email: christopher.nguyen@cshs.org

Learn More

Christopher Nguyen, PhD, received his bachelor of science in bioengineering from the University of California, Berkeley, focusing on applying diffusion MRI in the brain. He went on to obtain his master’s degree and doctorate in biomedical engineering from UCLA, developing clinically translatable diffusion MRI techniques to image the heart and abdomen. He completed his postdoctoral training in 2016 at Cedar-Sinai under the mentorship of Debiao Li, PhD.

Nguyen's research focuses on developing novel in vivo diffusion MRI techniques in the heart to interrogate the myocardial fiber architecture by characterizing the tissue microstructure. He is applying this technique to evaluate stem cell therapy, as well as risk stratify heart failure patients working alongside Cedars-Sinai cardiologists, Eduardo Marbán, MD, PhD, and Jon Kobashigawa, MD. Nguyen also focuses on translating his novel cardiac diffusion MRI techniques to other parts of the body such as the prostate to provide novel cancer imaging approaches. In collaboration with the Cedars-Sinai urologist, Hyung Kim, MD, Nguyen has developed a high-resolution diffusion MRI technique that targets early detection of prostate cancer in active surveillance patients.
