Megan Lewis is Associate Dean (Future Students), overseeing e-Science, the free, electronic magazine produced by the Faculty of Sciences.
She was Associate Dean (Research) in the Faculty of Sciences from 2010-2012 and previously Head of the Soil and Land Systems Discipline (203-2006).
Megan has an extensive background in remote sensing, vegetation ecology and environmental management. She has more than 30 years of experience as an educator at the University of Adelaide, Roseworthy Agricultural College, and the South Australian College of Advanced Education, teaching undergraduates and postgraduates in environmental science, natural resource management and geoscience, and providing in-service training for Australian and international professionals in spatial information science and environmental management.
QualificationsPhD, University of NSW, 2000 "Discriminating Arid vegetation Composition with Multispectral and High Spectral Resolution Imagery"
M. App. Sc. (Remote Sensing), University of NSW, 1993 "Land Cover Mapping for Barrow Island, W.A. using Landsat MSS"
M. Environmental Studies, The University of Adelaide, 1977 "Quantifying Arid Zone Recreation Impacts"
Megan teaches and coordinates courses in remote sensing and environmental mapping.
Remote Sensing III interprets image-based information gathered by sensors on space and airborne platforms. The course introduces the principles and application of remote sensing to a range of disciplines - environment, geoscience and agriculture. Practicals give 'hands-on' experience with image analysis software, including processing and interpretation for projects.
She has supervised over 17 Honours students, 9 of whom have been awarded First Class Honours. Opportunities for future Honours research projects are available in the Ecology, Evolution and Landscape Sciences booklet.
Postgraduate research students
Megan supervises and co-supervises a large group of PhD students in projects using remote sensing and spatial analysis tools for understanding terrestrial and marine environments. Current students are:
Tanya Doody - Quantifying water savings from willow removal in South East Australia
Adam Kilpatrick - Rangeland condition monitoring using remotely-sensed cross-fence comparisons
Erika Lawley - Mapping and monitoring land condition and its dynamics in arid Australia using satellite remote sensing
Victoria Marshall - Mapping and modelling the invasive weed, Buffel grass (Cenchrus ciliaris) in the Australian arid zone
Chittana Pomphila - Mapping and monitoring forest cover change in Lao PDR
Ramesh Raja Segaran - Spatial modelling of multi-function green space in the urban environment
Dorothy Turner – Fire regimes in desert Australia on a continental scale
2006 Winner, Asia Pacific Spatial Excellence Award for Excellence in Education and Professional Development
2006 Winner, Individual Award for Education and Professional Development, South Australian Spatial Excellence Awards
2007 Winner, Executive Dean of Sciences Prize and Award for Excellence in Teaching (staff with more than five years of teaching experience).
Research InterestsApplication of remote sensing and spatial data to environmental and agricultural management
Hyperspectral remote sensing for discriminating vegetation and landscape composition
Spectral properties of Australian plants and soils
Spatial patterns and temporal dynamics of Australian landscapes, in particular arid environments
This research has been funded by the Australian Research Council, Land and Water Australia, Environment Australia, Murray-Darling Basin Commission, Department of Industry, Trade and Commerce, SA Soil Conservation Council, SA Native Vegetation Council, Anglo-American Corporation and the South African National Research Council.
Megan Lewis is leader of the "Spatial Diagnostic Tools for the Deployment of Perennial Plants in the Landscape" project within the CRC for Plant Based Management of Dryland Salinity (http://www.crcsalinity.com/programs/index.php?disptype=projects&id=28) and a contributor to the "Rewards for Biodiversity" project in the Desert Knowledge CRC.
