Gorse fire at Southwold Common on May 7th 2017
Jean and I had lunch at the Harbour Inn on the Southwold side of the
River Blyth on May 7th,
starting at about 1.15. We left the Inn at about ten past two, and were in a prime position to
see the frightening development of the fire as it spread through the gorse from West to East.
I photographed the fire as it developed, and the full set of photographs can be found here.

I retired as Reader in Distributed Information Management on 30/9/2007, staying on as a Principal Research Associate for the academic year 2007-2008. I am now fully retired, and no longer able to accept PhD students. I still supervise undergraduates, and continue to be involved in some of Jean Bacon's research projects, in particular the work on Information Flow Control in the Cloud.
Research interests include distributed database systems, information retrieval,
active applications and access control (including RBAC for wide-area applications
with federated management domains, and also trust-based access control systems).
Until I retired Jean Bacon and I led the Opera project, which had EPSRC funded research grants
for the Multi-Service Storage Architecture (MSSA), the IMP Interactive presentation
support system, Active Systems, Global Computation using Events, Oasis Access Control, Access Control Policy Management, Business Contract Driven Applications, Securing Publish/Subscribe Information Flows (EDSAC21), Information Management for Patient Care (CareGrid) and the Transport Information Monitoring Environment (TIME-EACM).
A list of selected publications can be found here. For versions that can be downloaded see the
Opera group publication page.
