The Computer Science (CS) seminar series is an event hosted by the Mathematics and Computer Science Division at Argonne National Laboratory, usually on Tuesdays at 1pm Chicago time. The series invites a mix of speakers from within Argonne, as well as external speakers from the U.S. and all over the world. Seminar talks span the breadth of CS, with a particular focus on scientific computing, high performance computing, and related topics.
The CS Seminar is always looking for new speakers at all career stages! If you would like to give a seminar or suggest a colleague, please contact seminar organizers David Lenz (dlenz@anl.gov) or Neal Conrad (nconrad@anl.gov) for more information.
