science + engineering

Here is some information on my science and engineering training and experience. I have completed a PhD in environmental science, through the Australian Rivers Institute at Griffith University. My research focus was on spatial analysis of urban freshwater ecosystems. Through collaborations with economists using my ecological data I have also researched indices and indicators of ecosystem resilience to stress. I have also worked extensively in biodiversity assessment using spatial analysis for the Queensland Government.

I have published three academic articles on environmental issues, the latest of which addresses climate change. Combining my environmental science expertise and the economics expertise of my co-authors we used analytic tools from economics to consider whether the greenhouse gases that cause global warming are being measured accurately.

My research skills include the use of Geographic Information Systems (GIS) and coding in python, model selection and analysis using R, as well as ecological fieldwork, data analysis and scientific writing. I enjoy analysing and synthesising data, and presenting complex information in as simple a way as possible.

I investigated the scale at which protection and rehabilitation of urban stream riparian reaches is beneficial to stream ecosystem health given surrounding land use factors and in-stream and catchment barriers to ecological connectivity.

My Masters research focused on developing engineering design criteria for road crossings so that they have less impact on the passage of threatened Cherokee darters in the Etowah River Basin, Georgia, USA. This involved a field survey of sites to determine the level of impact on fish passage, and consultations with stakeholders to facilitate implementation of new criteria. I determined the experimental procedure, arranged field trials and field crew, and gathered physical measurements in streams. I also carried out statistical analysis of data and computer modelling of culvert hydraulics.
