Christopher Baker is interested in using mathematical modelling to help inform the way that we manage complex systems. He has primarily worked on environmental systems, where he had developed models of species interactions to predict how management of one species will affect other species. During his PhD, he worked extensively in solving optimal control problems for the control of invasive species. Bringing these two research aspects together leads to problems about optimising management of interacting species, which is an ongoing area of research. Species removal problems cover many areas of biology and Chris has worked across a wide range of them. These includes managing invasive predators, such as feral cats, and plants in Australia, the removal of diseased Tasmanian devils from isolated regions to create devil facial tumour disease free areas, and modelling the effect of antibiotics on microbes to develop treatment strategies that prevent the emergence of treatment resistant infections. He is currently a John Stocker Fellow at The University of Queensland.
