AutoMed project -
tools for data integrators and users of heterogeneous scientific data resources.
New digital technologies and applications are giving rise to increasing volumes and varieties of
information: in distributed heterogeneous databases, on the web, in mobile and pervasive
computing environments. Users may find it difficult to find the right information for their
purposes and to combine and reconcile information from different independent sources.
My research interests are in querying,
integrating, visualising and personalising heterogeneous information,
particularly as arising in learning environments, science and social science.
Current research interests include
intelligent support for learning and knowledge communities
flexible querying of complex data
data languages, data models, data quality,
query interfaces, query processing, query optimisation,
semi-structured data, semantic web,
system architectures and performance,
web information retrieval, information extraction.
Vacancies: Please contact me if you would like to collaborate
on any of the above or related areas. There are frequently funding
opportunities for PhD students, postdocs and visiting researchers.

After a BA in Maths at Cambridge and working at IBM Greece in
the early to mid 1980s, I returned to the UK to do an MSc and a PhD in Computer Science
at Birbeck. My PhD and postdoctoral research was in data models and languages.
I held a SERC Postdoctoral Fellowship at University College London during 1989-91
and then joined King's College London.
After eight years there as Lecturer and then Senior Lecturer,
I returned to Birkbeck as Reader in 1999 and Professor from 2001.
Since 2003 I have been Co-Director of the London Knowledge Lab,
a multi-disciplinary research institution which aims to
explore the ways in which digital technologies and new media are
shaping the future of knowledge and learning.
My current research is in querying, integration and personalisation of
information, with applications in e-learning and e-science.
