My research focuses on the development and application of mathematical models of agricultural systems. Currently, this involves two main strands:

- Working within the Water Friendly Farming platform of catchment-scale experiments located in the upper Welland in Leicestershire, my research combines hydrological modelling and experimental manipulations to problems of integrated catchment management, including natural flood management. The Water Friendly Farming experiments target design and testing of agricultural interventions that deliver co-benefits for downstream flood risk, sediment delivery to water as well as water quality (nutrients, pesticides) and aquatic biodiversity. Hydrological modelling is a key tool in optimising intervention measures, quantifying their effectiveness and understanding the processes that control the system.

- I am building on extensive research into the fate and effects of organic pollutants in the environment to develop novel approaches that underpin the safe use of agrochemicals. Again, this work links process-based experiments with field- and catchment-scale investigations and uses mathematical modelling to bridge across scales and integrate results into environmental risk assessment. My team has recently developed proof-of-concept for linking models drawn from different disciplines (individual-based pest models, crop root models, pesticide fate and toxicokinetic-toxicodynamic models) into a framework to drive innovation in development of pesticide produts. I am also working at the scale of agricultural landscapes to combine ecological and fate models to quantify population level-effects of pesticides on non-target species.
