I live in
where I am a professor in the
Management Group within the School of Computer
Science of the University
of Manchester, and the Director of Postgraduate Studies of our school. Before, I have been a member of the very nice
group of Franz Baader, the Chair for Automata
Theory at the Technical University in
Dresden, and many of the following links still point to Dresden.

My general research interests are in logics for knowledge representation
and automated deduction. More specifically, I am interested in
Description, Modal, and Dynamic Logics, the corresponding inference
problems, their complexity, and decision procedures for these problems.
Description Logics are a family of
knowledge representation formalisms with several nice properties such
as high expressive power, well-defined semantics, decidable inference
problems, and practicable inference algorithms for these problems. I
work on Description Logics as the logical underpinning of ontology
languages such as OWL and OWL 2; their
usage, for example, in molecular biology; practical inference
algorithms for highly expressive Description Logics; and on the
complexity of and inference algorithms for Description, Modal, and
Dynamic Logics, using
e.g., automata-based and tableau-based techniques.
I maintain a list of DL reasoners.
- I will give a course on Description Logics at the Reasoning Web Summer
- we have revamped the OWL in Manchester web site!
is a Knowledge Blog for
descriptive, tutorial and explanatory material about building, using
and maintaining ontologies, as well as the social processes and
technology that support this. So far, I have contributed, with
Robert Stevens, blogs on
OWL, a general one on OWL,
one on GCIs,
and one on pre- and post-coordination.
- our School of Computer Science was awarded a Centre for Doctoral Training, which provides students
with a novel way of working towards their PhD and comes with funding
for home and EU students! Additional, there is funding
available for all PhD students: you are cordially invited to apply!
- the Journal of Logic and
Computation has a corner on Logic for Ontology Engineering
, and you are cordially invited to submit a paper
Publications and talks
- An irregularly updated list of
my publications is available online, as well
as a shiny
DBLP Publication List. Also,
google scholar is so kind to maintain my citations.

- If you consider doing your Ph.D. in logic-based knowledge
representation, ontologies, or Description or Modal Logics, and would
like to do it within our great, cross-disciplinary IMG group and under my supervision,
please have a look at the
web page for future Ph.D. students and
let me know.
I teach, together with Bijan Parsia and the
friendly support of <oXygen/> XML
on semi-structured data and the Web;
together with Renate Schmidt, COMP61132 on
Modal and Description Logics;
and, together with Carole Goble, the Research Seminar COMP80122.
Schneider and I gave an introductory course on Description Logics at ESSLLI
Currently, I am co-supervising the following PhD students:
The following is a list of people with a PhD that I have had the great pleasure to co-supervise in the past: Birte Glimm, Matthew Horridge,
Peihong Ke ,

- Ian Horrocks and
me are developing practicable inference algorithms for very expressive
Description Logics. Some of our algorithms were implemented by Ian in
his automated reasoner FaCT and they are
being used in various modern DL
In the EPSRC project Composing and
decomposing ontologies: a logic-based approach, I have been working with Thomas Schneider, Ian Horrocks, Bijan Parsia, Dirk Walther, Frank Wolter, and (as a guest star) Carsten
I am an editor of the Logic for Ontology Engineering corner

of Automated Reasoning, was a PC co-chair of KR 2010, am a member
of the OWLED steering
committee, and the member of various PCs.

I gave tutorials at the Reasoning Web Summer School 2007 and at the ACIA Summer School 2007.
Carsten Lutz and
I gave a course on Description Logics at ICCL
Summer School 2005:
Logic-based Knowledge Representation .
Ian Horrocks and I gave
on Description Logics at IJCAR 2001 (slides can be
on Description Logics at ECAI2002; and
an introductory course
on Logical Foundations for the Semantic Web at ESSLLI2003.
Carsten Lutz and I
gave an advanced course
on Description Logics at ESSLLI2002, and an introductory
course on Description Logics at ESSLLI2004 in Nancy.
