University of Newcastle

Santosh Shrivastava
Santosh Shrivastava was appointed a Professor of Computing Science, University of Newcastle upon Tyne in 1986; he leads the Distributed Systems Research Group. He received his Ph.D. in computing science from Cambridge in 1975. His research interests are in the areas of distributed systems, fault tolerance and application of transaction and workflow technologies to e-commerce. He led ESPRIT basic research project BROADCAST and long term research project C3DS on service provisioning. His group collaborates and receives funding from Nortel Networks, British Telecom, Hewlett-Packard and IBM. Together with his colleagues he set up Arjuna Solutions Ltd in 1998 in Newcastle to productise transaction and workflow technologies developed by his group. Now part of Hewlett-Packard, HP-Arjuna Labs (www.arjuna.com) is a centre of excellence for transactional technology.

Paul Ezhilchelvan
Paul Devadoss Ezhilchelvan received Ph.D. degree in computer science in 1989 from the university of Newcastle upon Tyne, United Kingdom. He received the Bachelor of Engineering degree in 1981from the University of Madras, India, and the Master of Engineering degree in 1983 from the Indian Institute of Science, Bangalore. He joined the School of Computing Science of the University of Newcastle upon Tyne in 1983 where he is currently a lecturer. His main research interests are in the areas of fault-tolerance and distributed computing. He has published several research papers in the topics of distributed agreement protocols, replicated processing, scalable and reliable multicast protocols, and group membership in synchronous and asynchronous distributed systems.

Graham Morgan
Graham Morgan is a lecturer in the School of Computing Science. He received his PhD in Computing from Newcastle University in 2000. He was appointed to a Lecturer position in September 2000 and is a member of the Distributed Systems Research Group. His research interests are in the areas of distributed computing, group communications, fault-tolerant computing, real-time systems and Middleware software development. Recently, he has worked towards the development of protocols provided as Middleware services for satisfying real-time and consistency requirements for Internet based Auction applications and Networked Virtual Environments.
