Research expertise:
- Spray drift modelling of ground applications
- Turbulence modelling – Karhunen-Loevé Expansion
- Parallelisation of flood modelling software
- River and flood plain flood modelling
- Analysis of the frequency of extreme flood events
Current projects:
I am working on the FRST program: Integrated solutions to the fate of Agrichemicals, based on Biomarker Technology. I am on the project team that is developing the web-based software CART – Cumulative Agrichemical Residue Tracking. This software runs a spray drift mathematical model built of the region to enable users to manage the spray drift hazard.
