Martin is a postdoctoral fellow in the School of Geography, Planning and Environmental Management at UQ. He has a background in theoretical astrophysics, specialising in analytic & numerical models of cosmology and galaxy formation following a D.Phil at Oxford & Caltech. He has recently joined the group to apply this modelling experience to environmental systems. Though stars and endangered species may not seem to have much in common, both are governed by births, deaths, resources, competition and feedback. But though the Universe at large will be just fine for another 13 billion years, whether we can model it or not, the need to understand our ecological systems is a bit more pressing!
