I am a Reader in Computer Science at the University of Newcastle upon Tyne and a member of the dependability research group. I received my first degree in Mathematics from Cambridge University, followed by an M.Sc. and then in 1988 a Ph.D. in Computing Science from the University of Newcastle upon Tyne, for a thesis in the area of Distributed Systems. I have been involved in a number of European research projects on dependability, including PDCS-2, DeVa, MAFTIA and DSoS, and led MAFTIA (Malicious and Accidental Fault Tolerance for Internet Applications).

I am also involved with the EPSRC funded project DIRC, which is an interdisciplinary research collaboration on dependability. My research interests include security of mobile code, reflection, coordinated exception handling in concurrent/distributed systems, object-oriented systems, fault tolerance, and Internet technologies. I have published extensively on distributed systems and fault tolerance.
