I collaborated with Yose Widjaja to develop a 3-D interactive graph visualisation system capable of displaying graphs with large numbers of nodes and applied it to the visualisation of protein interaction networks. Paper:

I worked with Minghi Suryajaya to develop a locomotion system for virtual reality that allowed users to walk with a natural motion in any direction through the virtual environment and applied it to a mine simulation. Papers:

I worked with Guy Tsafnat to develop a representation for fields (spatially- and temporally- varying scalar, vector and tensor properties) and apply it to biomedical modelling. Papers published as a result of this work:

I am conducting research into the nature of such triangulations (which ones can be efficiently computed?), designing algorithms for their computation (can we find an algorithm for the efficient computation of the generalized Delaunay triangulation of a PSLG?), and measuring performance of triangulation algorithms (which published algorithm is fastest in practice?).

You can interactively try my algorithm for realizing a Delaunay triangulation.
