William Benton

William Benton provides technical direction for machine learning efforts in Red Hat Middleware and leads a team of data scientists and engineers.  After stints in academia doing HPC and static bytecode analysis, he vowed never to touch anything involving scientific code or the JVM again; in a pleasant professional irony, he’s liking both much better this time around.  Will lives in the midwestern United States with his wife and three children and spends some of his spare time chasing light on bicycles or capturing it with cameras.
