MSci (ANU)
PhD Student

Simon is a current PhD candidate at the ANU Fenner School of Environment and Society. His research is centered on understanding processes that drive gully erosion and sediment delivery to the Great Barrier Reef (GBR) lagoon.

Simon’s educational background is in Earth science and natural hazards with a specific focus on the application of remote sensing and spatial analysis for understanding Earth systems. He has worked as a spatial analysis research assistant at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and also a program officer (science) for the Australian Flood Risk Information Project at Geoscience Australia (GA).

In addition to his research studies, Simon is also an active tutor in both undergraduate and postgraduate science courses at the ANU. Courses he is currently, or has previously been, involved in include:

ENVS2004/6024 - Weather, Climate and Fire
ENVS3019/6319 - Advanced Remote Sensing and GIS
ENVS2015/6015 - GIS and Spatial Analysis, and
ENVS8003 - Climate Change Vulnerability and Adaptation

Thesis title: Spatial investigation of gully erosion in catchments adjacent to the Great Barrier Reef, Queensland

Thesis description:
My thesis is focused on understanding the spatial nature of gully erosion across catchments adjacent to the Great Barrier Reef (GBR), and what impact the sediments derived from these gullies are having on ecologically significant marine ecosystems of the GBR lagoon. I am supervised by Professor Albert van Dijk (ANU), and work in conjunction with CSIRO under the supervision of Dr Scott Wilkinson.

The broader aim of my research is to help develop the body of knowledge required to effectively decrease sediment runoff into the GBR lagoon, thereby improving the health of vulnerable sea grass and coral ecosystems.
