The University of Greenwich at the Old Royal Naval College

After the Navy vacated the site the University of Greenwich leased many of the buildings of what is now the Old Royal Naval College, and its Department of Mathematical Sciences moved into the new campus in 1999. In this chapter the authors, both of whom were members of the Department at the time of writing, describe the teaching, research and mathematics communication activities of the Department, showing how the Greenwich tradition of computational mathematics, together with a commitment to mathematics education and to outreach, continues in the twenty-first century.
