Research Profile

I studied Soil, Water and Atmosphere at Wageningen University, the Netherlands. Following my propaedeutic exam (cum laude), I continued this study in the specialization of soil science. After receiving my MSc degree in 2002, I started my PhD research at the Department of Plant Sciences at the University of California in Davis and at the Laboratory of Soil Science and Geology at Wageningen University. I received my PhD degree in 2007, soon after which I moved to Dublin, Ireland. Here I took up my current position at the Department of Botany at Trinity College, as research coordinator of the project “Managing soil organic C in Irish agricultural systems”.

In my research, I address questions about how changes in land use and atmospheric CO2 concentrations affect the flow of C and N through soils and the microbes therein. To do this, I have been using three different approaches. Firstly, I conduct incubation studies and analyses of biomarkers to assess the activity and composition of the soil microbial community. Secondly, I combine soil fractionation techniques with isotopic analyses to assess the size and turnover of soil C and N pools. Finally, I use meta-analytic techniques to synthesize findings in my field of research.
