Toby Hudson is a Senior Lecturer in Theoretical Materials Chemistry in the School of Chemistry at the University of Sydney. In 2008 he completed a Sydney University Postdoctoral fellowship. His D.Phil. was in Materials Science at the University of Oxford in 2000-2004, modelling neutron damage in metals for fusion reactors, and he continued at the Oxford Materials Modelling Laboratory for a postdoctoral year studying silicon nitride crystal interfaces. His undergraduate degree was a B.Sc.(Adv.) at the University of Sydney, majoring in chemistry and physics, with an honours year in computational chemistry (class 1 and university medal).

My research is currently focussed on the following areas:
- Determining how local rearrangement mechanisms in network liquids and glasses achieve stress relaxation, and hence flow. This will also give a detailed picture of how collective processes such as crystallization begin. (with Prof P. Harrowell, Usyd).
- Optimal dense packing of binary compounds. Combining data-mining and Monte Carlo methods, we have discovered some structures that are able to pack two-component hard sphere systems more densely than if the components were separated and close packed. We are currently optimising these structures, and will determine their contribution to the binary hard sphere phase diagram. This project has application to pressure transitions and densely packed colloidal systems such as opals.
- Improving structural search algorithms. Numerous artificial intelligence methods have been developed by computer scientists, but applying them to chemical structures is nontrivial. By importing chemically reasonable mechanisms and structures into these methods we are able to sample the structural configuration space fast enough to rapidly equilibrate, or identify ground state structures.
