Work experience

2008 - present
Research Scientist with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), within the Data61 business unit (Remote Sensing and Image Integration team). Amongst others, this position currently involves the use of image processing techniques for remote sensing data such as airborne and satellite imagery, as well as synthetic aperture radar (SAR). The focus is on the multi-sensor integration and analysis of spatial and temporal data in order to provide accurate information on environmental factors such as vegetation cover and land use, as well as their changes over time. These projects are carried out in collaboration with various industrial and governmental organisations in Australia and overseas.

Main research activities (current and past) are provided in the following list (further details and references for some of these projects are provided here):
  • Monitoring of water quality for inland waterbodies using remote sensing imagery, in collaboration with the NSW DPI Water office, as well as within the NAWRA framework
  • Radar remote sensing: data fusion of synthetic aperture radar (SAR) data with optical Landsat imagery for forest mapping and monitoring (part of the GEO Forest Carbon Task)
  • Statistical climatology: application of spatial Bayesian hierarchical models for the analysis of extreme weather events (such as precipitation, temperature, etc.), based on current and future projections of regional and global climate models (RCM/GCM)
  • Blending methodologies: assessment and further development of existing/new data blending methods for multiple remote sensing products
  • Model—data fusion techniques: data assimilation of soil moisture observations (remote sensing) with model estimates for water resources assessment across Australia (part of the WIRADA partnership between CSIRO and Australia's Bureau of Meteorology, see more info here)
  • Vegetation trends product: derivation and computation of vegetation trends across Australia since 1972 (part of Australia's National Carbon Accounting System, NCAS)
  • Sparse vegetation monitoring: classification of sparsely vegetated zones (5-20% canopy cover) across Australia since 1989 (part of NCAS)
  • Seabed mapping: development of spatial tools for mapping coastal seabed condition using acoustic swath data (multi-beam echosounder) and video data
2005 - 2008
Research Fellow within the Signal Processing Laboratory at the Western Australian Telecommunications Research Institute (WATRI), Perth, Australia. My research at WATRI dealt with various aspects of array signal processing, acoustic speaker tracking and speech enhancement. An example of the type of research I was working on can be found here. As part of my work at WATRI, I was involved in the Last Metre Problem (LaMP) research project carried out in collaboration with, and partly funded by National ICT Australia (NICTA).

Main research activities included:
  • Source tracking: acoustic speaker localisation and tracking by means of array signal processing and sequential Monte Carlo (SMC) methods
  • Voice activity detection: integration of VAD data into SMC algorithm for acoustic speaker tracking
  • Dynamics tracking: optimisation of dynamics models for speaker tracking using SMC and evolutionary algorithms
  • Room acoustics: reverberation modelling for the simulation of room impulse responses
  • Other research: speech onset detection for improved time-delay estimation; minimum statistics (noise tracking) for voice activity detection; circular array processing for angle-of-arrival speaker tracking; joint audio-video speaker tracking
2004 (3 months)
Research Engineer with National ICT Australia Ltd (NICTA). This work involved the implementation of a real-time algorithm for localising and tracking an acoustic source in reverberant environments, using an array of microphones. This algorithm was based on a particle filtering method using importance sampling, developed during my previous Ph.D. research. Some demonstration results from this application can be found here.
