I am an agriculture/environmental scientist with broad research interests on increasing the productivity, profitability and sustainability of agricultural production systems and natural ecosystems in Australia and else where and tackling emerging issues including climate change.

I work accross mutiple spatial scales which includes paddock to continental scale and use modern data science and process-based/simulation modelling approaches to analyse collated datasets. Such modelling approaches are essential component hence;

• better undertand drivers of complex inherent variablity in agro-ecosystems that limits the production capababilites
• manage agro-ecosystems in an effective manner in changing enviromental conditons
• use input resources in sustainable and economical manner
