Dr Kate Helmstedt

Biography
Dr Helmstedt's research expertise is in using operations research to guide smart decision making for natural resource and environmental management with the ultimate goal of guiding future management decisions towards cost-efficiency, transparency and defensibility. Ecological systems are incredibly complex, and changing how those systems interact and evolve can have unexpected implications. Dr Helmstedt builds mathematical models of coupled ecological, land-use, and economic systems to understand the mechanisms driving success, failure, and efficiency of management actions. Carefully, transparently, and defensibly planning management and policy interventions while acknowledging those complexities and the associated risks helps achieve better outcomes for the environment and society. Dr Helmstedt completed her PhD in 2015 at the University of Queensland under the supervision of Professor Hugh Possingham. She then spent two years as a postdoctoral researcher at the University of California Berkeley before joining QUT as a Lecturer.

Teaching
Prospective Honours and PhD students who are interested in any combination of biodiversity conservation, natural resource management, and operations research are encouraged to contact Dr Helmstedt -- especially those from groups traditionally underrepresented in mathematics. There are opportunities for competitive funding for domestic and international students through university schemes. Postdoctoral researchers pursuing their own funding are also encouraged to contact Dr Helmstedt.

Experience
Dr Helmstedt collaborates with diverse groups of scientists including mathematicians, statisticians, economists, ecologists, biologists, agricultural and marine scientists. These collaborative networks span Australia and internationally across the US and Europe (and, pending Brexit, the UK). Through ongoing collaborations with the Australian Antarctic Division and the Tasmanian state government, she helps guide decision-making about how to tackle the huge environmental problem of invasive species on islands.
