Biographical details
Asaph is a Future Fellow in the School of Chemistry. Prior to this he held appointments as an APD Fellow at the University of Sydney, a Visiting Scientist at the ETH Zurich, and a Postdoctoral Fellow at UC Berkeley and Lawrence Berkeley National Laboratory, where he was part of the Helios Solar Energy Research Center.
Research interests
Research in my group is focused on understanding the behaviour of soft matter – i.e. substances held together by relatively weak non-covalent interactions, such as liquids, gels and colloids – from a molecular and nanoscale perspective. The properties of these materials typically depend on the formation of beautiful structures that change with time. To study them we develop and apply analytical and computational methods based on statistical mechanics. We like to tackle questions that improve our fundamental understanding of matter while at the same time enabling the development of new advanced materials, with applications in areas including health and renewable energy. To inspire this work and to stimulate research on real physical systems we often work closely with experimentalists.
Questions that we are currently fascinated by include:
How do colloidal nanoparticles interact with one another and with interfaces, and how can these interactions be manipulated to enable the bottom-up assembly of new materials with applications in filtration, sensing and solar energy capture?
How does the shape of a molecule or colloid influence the symmetry of the crystals they form and the rate at which these crystals will grow?
What is the relationship between the subtle nanoscale order in gels and glass-forming liquids and their unusual viscoelastic properties?
How do defects diffuse in quasicrystals, i.e. in materials that have well-defined local order but which lack translational symmetry?
