BIOGRAPHY

Anthony Christodoulou is faculty in Radiology, Bioengineering, and Physics & Biology in Medicine at the University of California, Los Angeles (UCLA). Previously, he was Associate Professor of Biomedical Sciences and the Director of Magnetic Resonance Technology Innovations for the Biomedical Imaging Research Institute at Cedars-Sinai Medical Center (CSMC). He received his Ph.D. in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign (UIUC) and his B.S. and M.S. degrees in Electrical Engineering from the University of Southern California (USC).

Prof. Christodoulou’s research laboratory develops and translates novel magnetic resonance imaging (MRI) techniques through innovations in MR physics, machine learning, and image reconstruction. His group’s primary focus is on multidimensional quantitative imaging methods for the diagnosis, risk prediction, and treatment monitoring of cardiovascular diseases and cancer. He has authored publications in outlets including Nature Biomedical Engineering, Magnetic Resonance in Medicine, Journal of Cardiovascular Magnetic Resonance, Radiology, IEEE Signal Processing Magazine, and IEEE Transactions on Medical Imaging. His work on 4D cardiovascular MR (CMR) received the best paper award at the 2011 IEEE Engineering in Medicine and Biology Conference. His work on multidimensional quantitative cardiovascular imaging, dubbed MR Multitasking, received the 2016 Society for MR Angiography (SMRA) E. James Potchen Award for Best Oral Presentation, was a finalist for the 2017 Society for CMR (SCMR) Early Career Award, and received the 2018 SCMR Clinical Seed Grant Award.

Dr. Christodoulou is an Executive Board member of the SMRA, a Fellow of the SCMR, and a member of the ISMRM, IEEE, and AHA.
