My Expertise

My expertise is in geographic information systems (GIS). I apply GIS to real-world problems and help decision-making in a wide spectrum of humanitarian engineering problems, including red-flagging of epidemics and natural disaster management. GIS helps critical decision making and brings benefits to individuals and communities, especially to disadvantaged and marginalised people. I am recognised nationally and internationally as a GIS expert who is specialised in responding to outbreaks, disasters and relief efforts. For example, my publications include geospatial risk analysis methods to flag epidemics for urgent intervention, machine learning methods for bushfire susceptibility mapping, spatial clustering and modelling for landslides susceptibility mapping, social media data-based typhoon disaster assessment, and sugarcane yield prediction using a novel cross-validation approach.

My Research Activities

My main research interests are geographic information systems (GIS) and remote sensing (RS):

Geographic Information System (GIS) GIS is now more than ever an enabling technology for utilities and communications, transportation, public safety, natural resources, health and human services, etc. My main research is to apply GIS to real-world problems and help decision-making in the fields of asset/utility management, natural resources exploration, intelligent transportation, natural disaster and emergency management, and public health research. My publications include spatial and temporal fire occurrence patterns using landscape attributes such as climate, terrain, land use, etc. to develop a better understanding of wildfire occurrence across Australia, identifying the most significant attributes linked to fire occurrence, effective flood emergency plans and response measures, integration of spatial analysis and an agent-based model for shelter assignment and routing in flood scenarios, and risk analysis methods to flag epidemics for urgent intervention.

Remote Sensing (RS) Traditional photogrammetry and hi-resolution optical and infrared imaging systems continue to be important geospatial data acquisition technologies. Digital image capture systems are mounted on different platforms, such as hi-resolution satellites, aircraft, unmanned aerial vehicles, road vehicles, etc. Research areas include sensor calibration, direct georeferencing of sensors and automated feature extraction, as well as those related to a variety of mapping/imaging applications. My publications include deep learning from multispectral/hyperspectral images and data fusion of lidar point clouds and multispectral/hyperspectral images which are essential for the enhanced feature extraction from multi-layered datasets.
