Research Interests

Dr. Chen is a magnetic resonance imaging (MRI) physicist with research interest in fast image acquisition methodology, pulse sequence design, MRI artifact correction, and application of MRI to studies of neurological diseases. He has been developing novel high-resolution imaging protocols and analysis procedures for mapping structural and functional connectivity of brains. More generally, Dr. Chen's research involves the application of MRI in translational contexts. He has been serving as the principal investigator on NIH-funded R01, R21 and R03 grants, and has had extensive experience as a co-investigator on NIH-funded projects.
