Robert was responsible for 3 of the REF2014 Impact Case Studies submitted by the department of Computer Science. Each of these case studies was based on technology transfer and exploitation of research from the Real-Time Systems Research Group, undertaken by the start-up / spin-out companies in which he was involved (see Biography below). The REF Impact Case Studies can be found via this link to the REF2014 website.

The RapiTime impact case study was updated and used for REF 2021. The updated case study can be found via this link.



Robert received a DPhil in Computer Science from the University of York in 1995. Since then he has founded three start-up companies, all of which have succeeded in transferring real-time systems research into commercial product.

At Northern Real-Time Technologies Ltd. (1995-1997) he was responsible for development of the Volcano Controller Area Network (CAN) software library. This technology has since been widely used in the automotive industry, by Volvo, Jaguar, Landrover, Aston Martin, Mazda, and others. 

At LiveDevices Ltd. (1997-2001) he was responsible for development of the Real-Time Architect suite of  products, including a highly efficient, single-stack Real-Time Operating System (RTOS) Today, OSEK and Autosar compliant derivatives of this RTOS are used by the majority of the worlds leading automotive manufacturers and suppliers. The total number of deployed copies is now over one billion, and is increasing at a rate of 1-2 million copies per week. 

In 2002, Robert returned to research at the University of York, initially working in the Advanced Computer Architectures Group on AURA pattern matching technology. Today the AURA library is used extensively in research and also in a number of products that were marketed by Cybula Ltd.

In 2004, Robert re-joined the Real-Time Systems Research Group, where he was involved in setting up Rapita Systems Ltd., a spin out company, aimed at transferring worst-case execution time analysis technology into industry. Today this technology is used by leading Avionics, Space and Automotive companies.

In 2010, Robert returned to full-time research at the University of York.

In 2023, Robert semi-retired and now works 1 day per week.
