Research Interests
My main research interest is in the properties of nanometre scale particles (called 'atomic clusters') and in developing ways of building nano-electronic devices from these clusters - we are focused on neuromorphic computing ("a computer chip that thinks like the brain"). We also have a the only scanning tunneling microscope in NZ. This allows us to study novel nanostructures with atomic scale precision - we focus on topological instlators and related materials.
