Hal Cecil Charles
Adjunct Associate Professor in the Department of Radiology

Dr. Charles is an Associate Professor of Radiology, a chemist and an expert in MR imaging and spectroscopy with over 40 years of experience in nuclear magnetic resonance. He serves as the Scientific Director of the Duke Center for Advanced Magnetic Resonance Development. He has had extensive experience in conducting longitudinal clinical trials with MRI and MRS used as imaging biomarkers. He is also director of the Duke Image Analysis Laboratory which is active in conducting clinical trials in CNS disorders (schizophrenia, MCI, AD), cancer, osteoarthritis and lung disease using imaging based biomarkers. His lab has developed approaches for imaging lung function (ventilation and V/Q) in humans with 19F MRI.
