Overview

I am currently the Deputy Head of the Department of Materials and Head of Research. My research group investigates materials for energy generation in a broad sense, specifically targeting inorganic thin films and nanomaterials that are of use for a range of applications including  thermoelectric, photocatalytic, electrocatalytic and photovoltaic power generation. To acheive this, we typically use materials chemistry to design low temperature bottom up syntheses utilising molecular precursors that allow exquisite control of the chemical composition of materials, thus allowing us to tailor them toward a specific application. We also use various top down processing techniques such as liquid phase exfoliation of layered crystals to produce thin inorganic semiconductors which are complementary to graphene. Recently we have pioneered the use of these processes in serial to produce new synthetic two-dimensional materials. In  general, the use of solution phase pathways toward nanomaterials also allows us to take advantage of additive manufacturing processes, AACVD, spray coating and digital printing to assemble these inorganic materials into macroscopic structures and devices.  The group collaborates internationally with a range of materials scientists, chemists, and physicists to achieve these goals.
