Dr. Timothy Williams is the Deputy Director of Argonne’s Computational Science Division ([CPS](https://www.anl.gov/cps)). As part of the ALCF Catalyst team—computational scientists in that support and recruit production projects through the INCITE and ALCC programs—Tim has worked with a number of large-scale projects using ALCF’s suprecomputers, especially in the the area of plasma physics. He currently manages the ALCF Aurora [Early Science Program](https://www.alcf.anl.gov/science/early-science-program). Tim has been at Argonne since 2009, moving from ALCF to the newly-created CPS division in 2018. From 2000-2009, Tim worked as a quantitative software developer in the financial industry, writing pricing and risk software for Morgan Stanley in New York and Citadel in Chicago. From 1995-2000, he was a staff scientist at LANL’s Scientific Computing Group and Advanced Computing Laboratory, working on a C++ framework for parallel scientific computing. Starting as a postdoc in the Magnetic Fusion Energy group and Massively Parallel Computing Initiative at LLNL, and later on the NERSC staff; Tim spent 1989-1995 doing research in tokamak plasma turbulence and other areas, and developing a long-term interest in large-scale parallel computing.
