An Lab
Hongyu An, PhD, is a professor of radiology and director of the Biomedical MR Center (BMRC) for Mallinckrodt Institute of Radiology (MIR) at Washington University School of Medicine in St. Louis. Also the associate director of MIR’s Center for Clinical Imaging Research, An is renowned for her expertise in MR physics, pulse sequences and image reconstruction analysis. Her work has led to the first validated MR approach to measure cerebral oxygen extraction fraction in humans. This technique has helped answer key questions regarding the neuro-pathological impact of sickle cell disease in children, acute ischemic stroke and stroke risk prediction. An’s impressive publication record and robust extramural funding record highlight these advances. An received both her doctorate and master’s degree from Washington University, as well as a master’s degree from Academia Sinica in Beijing.
