• Comment: As discussed on #wikipedia-en-help. There are two major issues:
  1: In a biographic article *every* single piece of biographic information has to have an in-line citation, starting with the Early life. The entire draft has no in-line citations. This is a mandatory requirement.
  https://en.wikipedia.org/wiki/WP:INTREFVE you'll want to follow this tutorial which guides you on how to insert in-line citations.
  2: You haven't demonstrated how Paul meets our special criteria for inclusion, which you can find at https://en.wikipedia.org/wiki/WP:NACADEMIC
  Only people who meet that criteria can have an article on Wikipedia, and you haven't demonstrated how Paul meets the criteria. It's *possible* he meets it as being Director of Science for Argonne’s Leadership Computing Facility, but, again, there is no source to back this up so this has not been demonstrated. qcne (talk) 15:37, 4 March 2025 (UTC)

Paul C. Messina is an American applied mathematician and computer scientist known for his contributions to high-performance computing (HPC). He has held key leadership roles at Argonne National Laboratory and Caltech, including serving as the founding director of Argonne's Mathematics and Computer Science Division and establishing the Center for Advanced Computing Research at Caltech.^[1]

Messina was the Director of Science at the Argonne Leadership Computing Facility from 2008 to 2015 and the project director of the U.S. Department of Energy’s Exascale Computing Project from 2015 to 2017.^[1] He is an Argonne Distinguished Fellow and continues to serve as a senior advisor on strategic computing initiatives at Argonne.^[1]

Messina joined Argonne National Laboratory in 1973, where he held various positions until 1987 and became the founding director of Argonne’s Mathematics and Computer Science Division.^[1] In 1987, he moved to Caltech to establish Caltech’s Center for Advanced Computing Research, serving concurrently as the center’s director and as Caltech’s Assistant Vice President for Scientific Computing.^[1]

Messina directed the Department of Energy’s Accelerated Strategic Computing Initiative (ASCI) from 1998 to 2000.^[1] He was a senior advisor to the Director General of CERN from 2002 to 2004.^[1]

Messina has been instrumental in advancing high-performance computing for scientific and engineering applications. He led initiatives that deployed some of the world's most powerful supercomputers and supported computational science at extreme scales.^[2]

He contributed to the United States’ exascale computing strategy, outlining the project's goals and challenges in a 2017 publication.^[3]
