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:
Value-Added Data Systems, i.e., data
management principles, techniques, methodologies and tools to
support, in the context of big data, the complete cycle (from
extraction, through semantic integration, to querying) of data
provision that is sensitive to the user context and aims to find
best-fit solutions in the light of the data context (e.g.,
quality, provenance, etc.).
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
- In the dataspaces area, I was an active
member of a 36-month EPSRC-funded research
project on this topic that ran from Jul 2008 to
Jun 2011. The particular approach to dataspaces
that this project followed 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. The project built a
dataspace management system called
DSToolkit that, internally, uses
model-management operators to bootstrap a
dataspace and view-based rewriting to query
principles and architecture for value-added data systems

over diverse environmental sensor networks

Dataspaces: relying on user feedback to refine
and improve the outcome of automated schema
matching and schema mapping algorithms

I am gradually reducing my PhD supervision load as of 2015.
Note 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 take some time to explore.
I currently (jointly) supervise the following PhD
- (Feb 2016-to date) Lara Mazilu on
mapping generation at scale (with Norman Paton).
- (Feb 2016-to date) Alex Bogatu on
pay-as-you-go data cleaning (with Norman Paton).
- (Apr 2013-to date) Fernando Rene Sanchez Serrano on
pay-as-you-go integration of linked data (with Norman Paton).
- (Sep 2013-to date) Julio Cesar Cortes Rios on
active learning approaches to feedback-drive
improvement of dataspaces(with Norman Paton).
I have supervised to completion (mostly jointly) the following

The courses I'm often teaching are:
- (Year 1) Fundamentals of Distributed Systems
- (Year 2) Fundamentals of Databases
- (Masters) Querying Data on the Web
Unfortunately, the University's
policy is that all the
information about my teaching is only visible to the
students taking the courses.
The admin responsibilities I currently have are:
- Being PhD Tutor within the Research
- Helping to run the Mentoring Scheme for the
