Dianne Newman is a 2016 MacArthur Foundation Fellow and the Gordon M. Binder/Amgen Professor of Biology and Geobiology in the Divisions of Biology and Biological Engineering and Geological and Planetary Sciences at the California Institute of Technology (Caltech).
Dr. Newman’s research examines the relationships between bacterial metabolism, geochemistry, and infection. Her work has revealed how bacteria can mobilize arsenate in arsenic respiration and how anoxygenic phototrophs utilize ferrous iron during photosynthesis. She is a pioneer in molecular geomicrobiology who has contributed widely to understanding microbe-mineral interactions in the context of evolution of life on Earth. More recent studies by the Newman lab have expanded their investigations to bacterial communities in chronic infections, such as elucidating the role of phenazine redox cycling in the survival of Pseudomonas aeruginosa within the lungs of cystic fibrosis patients.
Dr. Newman received her Ph.D. in Civil and Environmental Engineering from the Massachusetts Institute of Technology and was a postdoctoral fellow in the Department of Microbiology and Molecular Genetics at Harvard Medical School. She became a faculty member at Caltech in 2000 and was appointed as a Howard Hughes Medical Institute Member from 2005-2016. She is a fellow of the American Academy of Microbiology and serves as an editor of mBio and eLife. Her awards have included the National Academy of Sciences Award in Molecular Biology (2016), the NIH Director’s Transformative Research Award (2012), the Eli Lilly and Company-Elanco Research Award from the American Society of Microbiology (2008), an Office of Naval Research Young Investigator award, and the David and Lucile Packard Fellowship in Science and Engineering.
