Researcher biography
My research focusses on soil health in cropping and pasture systems, specialising in soil carbon and soil organic matter dynamics, microbial ecology, and plant-soil interactions. I am interested in how agronomic interventions impact soil health and in developing methods to reverse soil fertility decline and build healthier, more productive soils. This includes understanding the impacts of tillage, cover cropping, crop rotational diversity, nutrient management, and organic amendments on soil functional processes and crop development and productivity.
I have extensive experience in designing and analyzing field and glasshouse experiments and implementing advanced statistical models using R. I have excellent verbal and written communication skills, maintain positive relationships with collaborators both nationally and internationally, and publish manuscripts in peer-reviewed scientific journals.
