Research Computing Services

Dr Paul Calleja is the Director of RCS, where he provides research computing services across all academic disciplines. Dr.Calleja obtained his Ph.D. in computational bio-physics at Bath University. After filling a post-doctoral research position at Birkbeck College, he moved into private industry, where he spearheaded early commercialization of HPC cluster solutions within the U.K.

Following six years in the commercial sector, where he led the market transition from proprietary SMP systems to commodity cluster-based solutions, Dr. Calleja returned to academia to lead the formation of a new HPC service at Imperial College, London. From there, he moved to Cambridge University, to form a new HPC service and to direct a major reorganization that has resulted in University-wide HPC capabilities with a novel pay per use cloud computing model. Cambridge University now boasts the fastest academic supercomputer in the UK. Dr.Calleja sits on numerous national and international HPC committees and advisory boards, as well as being a founding member of the UK HPC Special Interest Group.
