Dr Marcel van Oijen
I am a member of the Biosystem Dynamics Section at CEH's Edinburgh research site. My area of expertise is process-based modelling of all kinds of biological systems. I have made models of the effects on crops, grasslands, coffee-tree agroforestry systems and conifer forests of pests, pathogens, weeds, ozone, climate change and the availability of nitrogen and water. For fun, I made a cellular automata model of DaisyWorld (global biosphere-climate coupling) and a 3-D root branching model.
My current technical focus in modelling is on improving methods of uncertainty analysis and model comparison using a Bayesian approach.
Software use: MATLAB/Simulink, Mathematica
PhD (Wageningen, The Netherlands, 1991): "Identification of the major characteristics of potato cultivars which affect yield loss caused by late blight".
