He has been actively involved with the Open Archives Initiative (OAI) since its inception and was one of the authors of the OAI-PMH, OAI-ORE, ResourceSync and IIIF specifications.
He worked at Los Alamos National Laboratory before moving with arXiv to Cornell in 2001. Prior to working on arXiv, he worked in the Physics Department at Syracuse University in computational physics, a discipline in which arXiv has eclipsed conventional journals as the preferred means of scholarly communication. He has a PhD in physics from the University of Manchester, UK.
