Jim joined the EAS group in early 2015 from the University of Canberra / Monash University where he held Research Fellow and Senior Research Fellowships over a period of more than a decade. Prior to this Jim held a Post-doctoral Research Fellowships at the Patrick Center for Environmental Research in the Academy of Natural Sciences of Philadelphia, USA, and also at Macquarie University.
Jim’s primary expertise is in the disciplines of ecological statistics and modelling, freshwater and estuarine ecology, landscape ecology, and systematic conservation planning and optimization. He also has a strong theoretical understanding and extensive practical experience using a wide range of modern statistical and modelling methods. These include: Machine learning predictive models; spatial optimization (Zonation) and decision theory; Hierarchical Bayes models; Generalized linear and mixed models; spatio-temporal models; meta-analysis; survival analysis; time-series / change-point models, missing data / observation error models, multiple-response models; and various non-parametric methods.
Jim’s highly developed skills in statistical computing and data management, particularly using R, are invaluable to the EAS research group, however he is also very competent with ArcGIS, WinBUGS, Stata, Python, MS Access and many other specialised programs.
Jim’s work along with other members of the EAS group focusses on the development of an innovative decision support system that will assist DELWP in the allocation of resources for conservation planning and management activities.
Publications – Jim has more than 70 peer-reviewed journal articles.
