Personal profile
Research Interests
Paul N. Williams is a Lecturer in Soil & Environmental Biogeochemistry. Paul obtained his Ph.D. degree in Biological Sciences from the University of Aberdeen in 2007. Previous to working at Queen’s he has held Research Fellowships with the Chinese Academy of Sciences, Lancaster University and a Lectureship with the University of Nottingham.
Paul, an analytical and environmental chemist, has research interests orientated around the role of soils and rhizospheres in global food security. Specific interests and projects focus on the influence of soil dynamic processes and chemical speciation on trace element (both toxic and essential) uptake by plants, visualising rhizosphere micro-heterogeneity through high resolution measurements using DGT and DET techniques, and bettering in situ monitoring of the environment.
Techniques and methods that Paul uses include multi-element chromatography (IC-ICP-MS), laser-based analytical measurement (LA-ICP-MS), passive sampling (DGT, DET), optical sensors (colour ratiometric planar optodes), in-situ UV/vis spectrometry and XRF analysis.
