Barry I. Schneider (Fed)
Staff Physicist
Barry. I Schneider (b. 1940 in Brooklyn, New York) is a staff member of the NIST Applied and Computational Mathematics Division. In early 2014, he came to NIST as General Editor of the DLMF project after a long career at Los Alamos National Laboratory and the National Science Foundation. Schneider's current research interests span a broad number of areas of theoretical chemistry, atomic and molecular physics, numerical methods and high performance computing. His current principal focus is developing novel methods for the solution of the time dependent Schroedinger nist-equation in ultra-short, and intense laser fields. He has authored or co-authored 140 refereed papers and books and has given numerous invited talks in the US and abroad. Schneider has served as Chair and Co-Chair of the APS Division of Computational Physics and Few Body Topical group and has been the organizer of a number of conferences and invited sessions here and abroad. He also serves as a reviewer for a variety of journals inside and outside the US. In 2020 Schneider and Heman Gharibnejad, a research associate, were awarded the prize for best journal article in the Information Technology Division. Schneider, and a small team of other NIST staff, were awarded the Department of Commerce Bronze Medal recognizing their work in transforming NIST’s infrastructure for computing in the era of data-intensive science. The Bronze Medal is the highest recognition awarded by NIST.
