Personal profile

Biography

I am a Geographer, working across the areas of hydrology, geomorphology, Geographical Information Science (GIS) and remote sensing. My work is focused on advancing physical geography and our understanding of Australian landscape processes, particularly the impacts from changes in climate and human interaction with landscapes. I established and manage the Civil Aviation Safety Authority (CASA) licenced drone remote sensing group as Chief Remote Pilot for The University of Western Australia (CASA.ReOC.0628) and hold the institutional Remote Operators Certificate (ReOC). I manage and oversee the Remotely Piloted Aerial Sensing Platform and drone operations across the Faculty of Science at UWA.

I did my BSc (Hons) and PhD (2007) in Geography at The University of Western Australia, and have held Teaching and Research Lecturing positions at The University of Queensland and now at UWA. I have a Graduate Certificate in Higher Education (GCHEd) from UQ (2011)

I previously served on the Editorial Panel of Journal of Hydrology and currently for Geographical Research. I am Treasurer of the Australian New Zealand Geomorphology Group (ANZGG).

Research

Theme 1: Hydrology, geomorphology and ecohydrology of wetlands and catchments under pressure from climate, humans and resource condition changes including land degradation, with a focus on Australian landscapes.

Geomorphology, hydrology and biogeomorphology:

  • Advancing our understanding of geomorphology, particularly biogeomorphology in dryland Australian rivers and response to changing hydrology and land degradation
  • Improving our understanding of remote-area hydrology and ecohydrology of large, remote and data-scarce dryland river basins, including management of dryland rivers and wetlands impacted by land management, resource condition degradation and climate change
  • Alpine hydrology and sediment transport processes, including response of the marginal Australian snowpack to a warming climate and processes of sediment transport, redistribution and accumulation and impacts of silver used in cloud seeding to enhance snow precipitation

Australian climate and hydrology across the Quaternary:

  • Palaeoclimate, snow hydrology and climate drivers of the Snowy Mountains
  • Climate dynamics and cyclone frequency during the human occupation of north western Australia

Climate variability and climate change impacts on biodiverse and alpine ecosystems:

  • Woodlands and Wetlands of biodiverse SW WA
  • Snowpack dynamics and snowmelt in the Australian Alps
  • Climate impacts and dynamics in carbon-rich coastal wetlands

 

Theme 2: Innovation and new knowledge for studying physical geography and environment processes.

  • Using Unmanned Aerial Vehicles (UAVs, or drones) for remote sensing of environmental processes in natural and agricultural landscapes, including improved methods for low-level remote sensing and Structure-from-Motion (SfM) point cloud data analysis
  • Distributed Temperature Sensing (DTS) using optic-fibre cable for high resolution spatio-temporal measurement using temperature directly and as an environmental process proxy
  • GIS and spatial analysis and remote sensing of hydrological processes, to study the hydrology of data-poor and dryland landscapes
