My current research interests include
virtual reality, control theory, robotics, and modelling of biological systems. In the past I have also worked on
term rewriting, graph rewriting, higher order rewriting, category theory,
concurrency and functional languages.
Numerical modelling of plant growth
In collaboration with
and others I am developing models of plant growth
based on numerical solution of differential equations
for elasticity, growth, and diffusion.
Real-time procedural humanoid animation
I have been involved with the
ViSiCAST and eSign
projects, and am currently working on the
whose aims are
automatically generated virtual deaf signing for broadcast television
and web sites.
I designed and implemented SiGML (Signing Gesture Markup Language),
an XML language based on the Hamburg Notation System for
describing the physical components of signs, and developed algorithms for
avatar-independent real-time procedural
animation of signs described in SiGML.
Currently I am working on an improved version of SiGML with a simpler
structure, to be applicable to a wider range of human movement.
theory and robotics
control theory is a branch of control theory due to William Powers
which appears highly suitable to the study of living organisms. As a
demonstrator project in the use of PCT to design the control architecture for a
complex control task, I am constructing (as yet only in simulation) a
based on PCT principles.
I have in the past been involved in the
- Reanimation of combat
simulation log files for after-action review.
(Collaboration with Defence Evaluation Research Agency (DEFRA).)
This involved analysing log files from combat simulators and
generating a virtual reality movie of the action in VRML.
- Virtual reality modelling of
landscapes, for visualising the predicted effects of landscape management
policies. (In collaboration with Andrew Lovett in the
School of Environmental
