Our main interest is in the relationship between the structure and properties of solids. We study the geometric reasons for the chemical activity of solids and the relationship between local order and physical properties, using mathematical techniques and computer graphics. We use solid-state nuclear magnetic resonance spectroscopy (NMR) to examine molecular sieves, minerals, layered materials, fullerenes, ceramics and biological materials.

The G minimal surface divides space into two interpenetrating labyrinths (coloured red and green).

Specific projects:

Periodic minimal surfaces (surfaces with zero mean curvature), which appear in a variety of inorganic, organic and biological structures, and the associated mathematical problems.
Morphogenesis (the origin of shape and form).
Systematic enumeration of crystalline networks using mathematical tiling theory.
Graphite, graphite oxide and graphene.
Synthesis and characterization of microporous and mesoporous molecular sieves.
Synthesis and characterization of metal-organic frameworks (MOFs).
