  • Research Interests

     I study molecular and physiological basis of plant nutrition and abiotic stress tolerance. My main area of interest is understanding the molecular basis of how nutrients including water are transported by the plants and how abiotic stress affects these functions. My current research involves understanding the function of GABA-gated anion channels in plants and GABA signalling under abiotic stresses such as acidosis, alkalinity, Aluminium toxicity, salinity and drought.  I work in the laboratory of Prof. Steve Tyerman. Our research uses  molecular, physiological and electrophysiological techniques (electrophysiology, patch clamp etc).
