When faster supercomputers aren’t enough

When a million veterans shared their genetic data by enrolling in the Department of Veterans Affairs' “Million Veteran Program,” they expected nothing back. This did not surprise Ravi Madduri, a senior scientist with the Data Science and Learning Division at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.
