John Mitchell, PhD

John Mitchell is a senior scientist and leads the Emerging Materials Group at Argonne National Laboratory.

John received his AB summa cum laude from Cornell University in 1987, and as a Hertz Fellow, his PhD from the University of Chicago in 1993 for theoretical studies of defect structures and order-disorder transitions of early transition metal chalcogenides. From 1993-1996, he was a DOE Distinguished Postdoctoral Fellow at Argonne’s Materials Science Division, where his research involved synthesis of superconducting cuprates and then synthesis and crystal growth of rare earth manganites exhibiting colossal magnetoresistance. Appointed to the staff in 1996, his current research emphasizes strategic synthesis, crystal growth, and structural studies of correlated-electron transition metal compounds using neutron and x-ray scattering. Mitchell is author or co-author of more than 300 peer-reviewed articles in scholarly journals. He has coordinated the development team for a high-resolution powder diffractometer at the Advanced Photon Source. He has also led a project in the DOE Center of Excellence in Synthesis and Processing entitled “Spin Polarized Transport in Complex Oxides.” He was awarded the DOE Early Career Award and the Presidential Early Career Award for Scientists and Engineers in 1999 and 2000, respectively. He received the University of Chicago Distinguished Performance Award for Argonne Scientists in 2006. He is a fellow of the American Physical Society, a fellow of the Institute of Molecular Engineering at the University of Chicago, and an adjunct professor in the Materials Science and Engineering Department at the University of California, Santa Barbara.
