Kawtar Hafidi is Associate Laboratory Director for Physical Sciences and Engineering. She oversees the laboratory’s research programs in physics and high energy physics, materials science, chemical science and engineering, and nanoscience and technology.

John Arrington joined the Medium Energy Physics group in 1998 and is interested in understanding the quark/gluon structure of matter.  His experiments utilize scattering of relatively high energy particles from protons, neutrons and nuclei to study their internal structure. 

Supratik Guha is the director of the Nanoscience and Technology division and the Center for Nanoscale Materials at Argonne National Laboratory, and a Professor at the Institute for Molecular Engineering at the University of Chicago. He is also the Senior Scientific Advisor to the Director at Argonne.

Salman Habib is the Director of Argonne’s Computational Science (CPS) Division, leading the overall day-to-day management, strategic direction, growth, and vision into both the near and long-term future. He holds a joint position in Argonne’s Physical Sciences and Engineering (PSE) Directorate, the Kavli Institute for Cosmological Physics at the University of Chicago, and the Northwestern Argonne Institute of Science and Engineering (NAISE). He also leads the ExaSky effort within the U.S. Department of Energy’s Exascale Computing Project. Salman’s interests cover a broad span of research, ranging from quantum field theory and quantum information to the formation of cosmological structure. He is particularly interested in innovative uses of high performance and data-intensive computing in solving scientific problems.

Dr. Cynthia Jenks has more than 10 years of leadership experience in science management and strategic planning, in addition to a background in both the chemical sciences and chemical engineering. Dr. Jenks’ research areas of expertise include surface structure and reactivity, surface structure-property relationships, catalysis, chemical conversions for sustainable energy, and thin film growth.

John F. Mitchell is an Argonne Distinguished Fellow and Interim Division Director of the Materials Science Division at Argonne National Laboratory. He received his A.B. from Cornell University in 1987 and his Ph.D. from the University of Chicago in 1993 for theoretical studies of defect structures and order-disorder transitions of early transition metal chalcogenides. His current research emphasizes strategic synthesis, crystal growth, and structural studies of correlated electron transition metal oxides and chalcogenides using neutron and X-ray scattering.

Venkat Srinivasan is the director of the Argonne Collaborative Center for Energy Storage Science (ACCESS) and deputy director of the Joint Center for Energy Storage Research (JCESR, the battery ​“Hub”). He is a former staff scientist at Lawrence Berkeley National Lab. His research interest is in developing next-generation batteries for use in vehicle and grid applications, among other things. Dr. Srinivasan and his research group develop continuum-based models for battery materials and combine them with experimental characterization to help design new materials, electrodes, and devices.
