Background
Guy Kirk joined Cranfield in February 2003. Before that he spent 13 years at the International Rice Research Institute (IRRI) in the Philippines, initially as Soil Chemist and later as Head of the Soil and Water Sciences Division. Before IRRI he did doctoral and post-doctoral research in the Soil Science Laboratory, University of Oxford, and between IRRI and Cranfield he was on sabbatical in the Department of Plant Sciences, University of Cambridge. He is Associate Editor of European Journal of Soil Science, and a Fellow of the Royal Society of Chemistry.Current activities
Professor Kirk's research focuses on physical, chemical and biological processes in soils; how to quantify soil properties and functions; and how to model soil systems at scales from the microbial to the continental.
