G. Allan Johnson is the Charles E. Putman University Distinguished Professor of Radiology at Duke University, with concurrent appointments in Physics (Trinity College of Arts & Sciences) and Biomedical Engineering (Pratt School of Engineering). He serves as Director of the Duke Center for In Vivo Microscopy, an NIH/NIBIB national Biomedical Technology Resource Center focused on developing preclinical imaging technologies and applying them to critical biomedical questions.
- Ph.D. in Radiology from Duke University (1974)
- Current leadership in preclinical MRI and connectomics
His research spans high-resolution magnetic resonance imaging, diffusion MRI, and structural connectomics, with applications to neurodegenerative diseases, brain development, and biomedical engineering. Recent work includes creating multicontrast MR atlases for rodent brains and pioneering ex vivo MRI-histology fusion techniques.
Selected publications reveal expertise in diffusion tensor imaging, tractography, and multimodal imaging workflows for both preclinical and clinical applications. Grants include leadership in projects funded by the CHDI Foundation (Huntington's disease), University of Pittsburgh (connectome atlases), and University of Tennessee Health Science Center (Alzheimer's imaging genetics).
Scientific recognition includes
- NIH/NIBIB Resource Center Leadership
- Charles E. Putman University Distinguished Professorship
His team at the Duke Center for In Vivo Microscopy develops multiparametric imaging platforms, 4D cardiac micro-CT atlases, and quantitative susceptibility mapping methods for applications ranging from neurotoxicology to plant root imaging.
