Robert Latham, ANL Robert Latham, as a Research Software Developer at Argonne National Laboratory, strives to make scientific applications use I/O more efficiently. After earning his BS (1999) and MS (2000) in Computer Engineering at Lehigh University (Bethlehem, PA), he worked at Paralogic, Inc., a Linux cluster start-up. His work with cluster software including MPI implementations and parallel file systems soon led him to Argonne. His research focus has been on high performance IO for scientific applications and IO metrics. He has worked on the ROMIO MPI-IO implementation, the parallel file systems PVFS (v1 and v2), Parallel NetCDF, and Mochi I/O services.
