I'm appointed as a research fellow, funded by an ARC Future Fellowship. My research spans theoretical, methodological, and applied ecology, reflecting my broad interest in biodiversity and conservation and my attraction towards quantitative methods. 

In relation to methods, I have been exploring ecological applications of new methods developed in machine learning and statistics. My main interest has been in predicting distributions of species, communities and diversity, focussing on how best to use new methods, and providing introductory guides for the ecological community. Published results include papers and related tutorials for several regression-related methods, including generalised linear and additive models (GLMs and GAMs), multivariate adaptive regression splines (MARS),  boosted regression trees (BRT) and MaxEnt. I am also contributing to books including one on machine learning methods for ecology. 

Most recently I have started working on problems associated with modelling non-equilibrial situations, exploring appropriate methods for predicting both the potential spread of invasive species and the likely responses of the biota to climate change. This has included research on linking mechanistic and correlative models with Michael Kearney (Zoology, University of Melbourne), on modelling invasive species, and on linking population and correlative models (with Keith, Wintle et al).

On the theoretical side, I am interested in how to robustly evaluate models and their predictions in ways that are appropriate for intended  applications, and how to deal with uncertainty and its impacts in conservation decision-making. 

Because I'm keen to ensure this work is relevant to real-world situations, I have also been involved in a range of conservation and resource management applications. These include modelling patterns of vegetation in NSW forests and species turnover in New Zealand rivers, providing advice to the Murray-Darling Basin Commission on the data infrastructure required for robust modelling in river ecosystems, and advising government departments on use of models for particular environmental and biosecurity issues.  Currently I'm  co-leading a linkage project finding robust strategies for restoring aquatic and riparian biodiversity.

Across these strands of work I've dealt with many types of data across a wide range of ecosystems, and at widely varying spatial scales: rare shrubs and floodplain vegetation in NSW, biological soil crusts in western Victoria , fish in Victorian rivers, cane toads in northern Australia; trees, shrubs, birds, reptiles and mammals  from 6 regions of the world; New Zealand marine and freshwater fish, and clownfish on coastal reefs in Papua New Guinea. I work with various students, including PhD students Cassia Read (the role of biological soil crusts in ecosystem function), Lucy Robinson (UQ; species distributions in marine systems) and Laura Shirley (the ecology and biogeography of eucalypts of the Grampians).

Collaborations

Collaborating with colleagues is one of the pleasures of this work, and I'm lucky to have had many opportunities:
  • an NCEAS working group focusing on modelling presence-only data from herbaria and museums led by Town Peterson and Craig Moritz, prompted much shared work, and particularly with Catherine Graham, Simon Ferrier and Steven Phillips. Steven and I have ongoing active projects
  • the Swiss workshops (above) led to work with John Leathwick and Trevor Hastie, Simon Barry, and Antoine Guisan.  If you want to contact John Leathwick about any of the papers we've co-authored, his email address is: jleathwick@doc.govt.nz
  • the German workshop has created ongoing links with Boris Schröder and Carsten Dormann
  • our lab works with Atte Moilanen (Helsinki, Finland) and sometimes I have the pleasure of joining with him on spatial prioritization projects; also with David Keith from DECC NSW
  • I've been involved in an NCEAS working group looking at the use of machine learning methods in ecology - led by John Drake and Bill Langford. And I'm currently involved in a new one, on predictor variables for modelling, led by Brian McGill.
  • I've starting working on climate change/invasive species problems, which brings connections to Mike Kearney, Brendan Wintle, David Keith, Colin Yates, Barry Brook and Stephen Williams.
  • and last but not least I share an office with Terry Walshe who is the deputy director of ACERA and a great roommate.
