Dr Robert Mullins’ research and teaching focuses on computer architecture and Very-Large-Scale Integration (VLSI) design. He is particularly interested in how real performance gains can be maintained as fabrication technologies approach the atomic scale and processor architectures are forced to become increasingly parallel. His recent work has focused on the design of efficient on-chip interconnection networks and a novel parallel processing fabric (Loki).
His doctoral research and early work in the Computer Laboratory involved the design and implementation of asynchronous microprocessors. This work also examined the benefits of asynchronous logic from a security perspective.
He is a Fellow of St. John's College, where he is Director of Studies for Computer Science. He is also a co-founder and trustee of the Raspberry Pi Foundation, a UK charity that aims to promote the study of computer science and electronics at the school level
