Megan graduated from the University of Adelaide with a Bachelor of Science (Honours in Botany) in 1997. From 1998 to 2003 she worked as a Research Assistant at The Australian National University with Assoc. Prof. Susan Howitt investigating the structure and function of plant ammonium and sulphate transporters. Megan then returned to the University of Adelaide to do her PhD on a project investigating the physiological characterization of grapevines in response to drought stress and the role of aquaporins, supervised by Professor Steve Tyerman and Assoc. Prof. Brent Kaiser. Following her PhD, Megan had a post-doctoral position at The Australian National University where she studied bicarbonate transport processes in cyanobacteria (blue-green algae). From 2009 until 2013, she worked as a research fellow at the University of Melbourne node of the Australian Centre for Plant Functional Genomics studying the effect of salinity on root growth in barley. In 2014, she was awarded an ARC DECRA fellowship to continue her research investigating salinity stress tolerance mechanisms in barley roots at the University of Adelaide. In April 2015 she joined Steve Tyerman’s group within the Centre of Excellence in Plant Energy Biology.
Megan’s research interest is in the area of abiotic stress (salinity, drought) tolerance in agricultural crops. 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 (ie. metabolomics). Her current research aims to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley (Hordeum vulgare L.) 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. We are also using a novel method, electrical impedance spectroscopy, to measure root growth in a number of wheat genotypes in response to salt-stress.
