Megan is a Senior Lecturer / Mortlock Fellow at the Waite Campus, University of Adelaide. She gained her PhD in Plant Biology at The University of Adelaide and is a previous recipient of an Australian Research Council Discovery Early Career Researcher Award.
Her research is focussed on improving crop yields in hostile soils (salinity, drought) and enhancing food security. Of particular interest to her is the ability of the root system to adapt to abiotic stress and maintain growth, increasing root soil exploration for nutrient and water uptake. Her expertise includes root biology, plant physiology, plant biochemistry, molecular biology and functional genomics. Her current research aims to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley as a cereal model. The knowledge gained in barley will provide important information for increasing salinity tolerance in other Australian cereal crops, most notably wheat.
Megan has been an active member of the Australian Society of Plant Scientists serving on the committee as a discipline representative for the past four years. She is active in promoting STEM to the wider community through events such as National Science Week and is passionate about promoting diversity and inclusion. She hopes to inspire the next generation of plant and agricultural scientists through her teaching at the University of Adelaide.

Megan’s research interest is focussed on understanding environmental stress tolerance mechanisms in agricultural crops. Environmental stresses such as drought and soil salinity cause major crop yield losses in agriculture, significantly impacting on agriculture sustainability. Soil salinity is estimated to affect more than 800 million ha of land (FAO, 2008). Currently, 67% of the land affected in Australia is in the cereal (wheat, barley) growing regions, particularly impacting south-western and south-eastern Australia. Dryland salinity significantly reduces crop yields and is estimated to cost the Australian farming industry around $1.5 billion a year.
Two major factors are driving the need to improve agricultural yields. The first is climate change, which means that wheat and barley are grown in increasingly hostile environments with soil salinity and drought both expected to increase this century, reducing the availability of arable land. The second is the increase in global population, expected to reach 9 billion by 2050. An increase in global agriculture productivity will be needed to meet the increase in demand for global food supply.
Megan's research is aimed at understanding the mechanisms that allow crop root systems to adapt to salinity and drought, thereby maintaining root growth and increasing soil exploration for nutrient and water uptake. Her current research aims to identify the molecular mechanisms that control and regulate root adaptation in response to salinity using barley (Hordeum vulgare L.) as a cereal model. This research will allow the identification of root traits that can be incorporated into breeding programs to develop higher-yielding salt-tolerant crops.
Salt Tolerance in Grapevines
Megan is also using grapevine as a model system to understand salt and water movement through plant systems; from the root to shoot. She aims to answer the question of how salt moves across the different tissues and major organs, how salt accumulates in root, leaf and shoot cells, and how movement and accumulation is controlled by the diversity of transport mechanisms operating in plants. This will be incorporated into biophysical models, to quantify the movement of salt through plant organs, tissues and cells, from root to leaf.
