Personal profile

Biography

I received my PhD from the University of Bayreuth, Germany in 2005. During my PhD, I investigated how do the apoplastic barriers, made of suberin and lignin, in rice and corn roots alter radial water and solute transport into the stele. After successfully completing my PhD under the supervision of late Prof. Dr. Ernst Steudle, I secured a postdoctoral research fellow position at Prof. Carol Peterson’s lab, University of Waterloo, Canada. At this stage, my research took a new direction, in which I was fascinated by plant anatomy and histochemistry. In 2007, I was awarded a prestigious Alexander-von-Humboldt fellowship from Germany and moved to Prof. Dr. Lukas Schreiber’s lab at the University of Bonn as a Humboldt research fellow. During my stay in Bonn, I gained a thorough knowledge in biochemistry, exploring the biosynthesis pathways of secondary cell wall polymers, such as suberin and lignin. I also pursued my interest in stress physiology to understand how biotic and abiotic stresses alter apoplastic barrier development in roots of crop plants. Four years later, I moved to Prof. Steven Rothstein's lab at the University of Guelph, Canada as a research associate to improve my knowledge in molecular genetics. My research was based on understanding plant responses to nitrogen limitation for the improvement of nitrogen use efficiency in economically important crop plants. In 2016, I moved to the University of Western Australia, and currently work on fascinating research projects to understand the efficient phosphorus acquiring and utilising mechanisms of iconic Australian native plants (specially, Proteaceae) which thrive on phosphorus-impoverished, weathered soils. In June 2017, I have been awarded a prestigious ARC Future fellowship to continue my research on Australian native plants.
