My research is centred on advanced information management. My main contributions fall in the area of advanced databases and advanced query processing.
My current interests are:
- Databases and Dataspaces, especially query processing and optimization, and query-based techniques for data integration.
- In the broader context of advanced databases, I am currently interested in the resurgence of massively-parallel approaches to data management, as exemplified by data appliances and by the map/reduce approach to cluster-based computing.
- In the dataspaces area, I am an active member of a
36-month EPSRC-funded research project on this topic that started in July 2008. The particular approach to dataspaces that this project follows is the intensive use of metadata and of user feedback for continuous improvement of semantic judgements thereby maximizing their utility for the purposes of querying dataspaces.
- Data Management of Streams and Sensor Networks, especially query processing and optimization that reconcile different objective functions, and query-based techniques for data integration.
- In a recent (Oct 2005-Sep 2008) EPSRC-funded research project, called
DIAS-MC, I have been active in developing a sensor network query
processing infrastructure, called SNEE, that is distinctive in
construing a sensor network as, strictly, a distributed
computing platform. Thus, SNEE query plans are fragmented and
executed in specific nodes in a truly distribued manner. Routing and scheduling take place at the level of query fragments. SNEE generates code for a target sensor network software layer (currently, nesC/TinyOS).
- A 36-month EU-funded research project in this topic
has started in September 2008, called SemsorGrid4Env. The main focus will be on enabling the construal of sensor networks in environmental monitoring as fully-fledged data resources amenable to high-level, view-based, semantic integration, thereby allowing rapid developement techniques (e.g., mash-ups) to draw data from sensor networks inn emergency response scenarios.
- Adaptive/Autonomic Systems, especially in query processing and in workflow management.
- I have been an active team member in two EPSRC-funded projects, one still ongoing, whose goal has been to investigate principled ways of developing generic adaptive systems technology in the areas of query processing and workflow execution.
- In this area, I am currently interested in
quality-of-service-driven adaptive strategies that use
utility functions to act with global scope in a coordinated fashion and in a principled manner.
Current
-
SemsorGrid4Env: applying semantic-grid ideas to allow mash-ups over diverse environmental sensor networks (project funded by the European Union, started September 2008, for three years, partners in Madrid, Athens, Southampton).
-
Dataspaces: relying on user feedback to refine and improve the outcome of automated schema matching and schema mapping algorithms (project funded by the UK EPRSC, started July 2008, for three years).

I welcome enquiries from prospective PhD students
interested in working in my current areas of
interest. I maintain descriptions of specific PhD
projects I'm interested in supervising (but don't assume
that I'm only interested in those PhD projects). Note, however, that you should have
considered the question of funding your studies
beforehand, as, in general, the School of CS in
Manchester does not devolve to academics the power to
grant studentships of any kind. On all matters
regarding doing a PhD in the School of CS, go to Postgraduate
Research and expand
the entry in the navigation bar to the left.
I have supervised to completion (sometimes jointly) 8 PhD students
and more than 25 MSc students in the course of my career. I currently supervise (often jointly) 4 PhD students.
