I am a research scientist working for Rothamsted Research for sustainable grassland agriculture in the UK. I collate farm management data and translate it to scientific data, and apply it to simulating the interactions of agricultural systems. What this means is I can provide future scenarios under different management systems or climate changes. I have RP Bio and CBiol designation.
Process modelling : Systems modelling in a variety of agricultural and environmental processes and statistical analysis of simulations against obervations.
- Systems modeller in soil-plant systems and processes, interdisciplinary in plant physiology, soil water, nutrient cycling and climate. Have operated various models (DNDC, SimDAIRY, NGAUGE and now DayCent). Also modify code for soilwater, crop growth and nutrient modules of integrated agro-environmental models. Working with North Wyke scientists on studies related to sustainable agriculture, management for soil health and food production whilst minimizing pollution losses.
- 12 years experience formulating or modifying models which describe climate and water limited growth of crop species
- 4 years experience in statistical downscaling of Global Circulation Models to regional climate scenarios
- 2 years experience of modelling snowpack accumulation, snowmelt and riverflow under climate change
I also have some experience in remote sensing and GIS
- Manipulation of remotely sensied imagery of forest degradation and vegetation
- Use of ArcGIS in display and extraction of data including remotely sensed images
- Use of CROPSCAN hand-held 16 band radiometer
Experience in various Windows software: Microsoft Office, programming in Fortran and Pascal/Delphi, Genstat statistics software, ERDAS Imagine image processing software and ArcGIS. Currently learning R and the Daycent agri-environmental systems model.
