Professor of Agronomy, Wickersham Chair of Excellence in Agricultural Research
Design/implementation/statistical analysis of field and controlled environment experiments on nutrient budgets and soil-plant nutrient cycling process in cropping systems including sampling strategies and designs for spatio-temporal considerations, environmental C and N losses and crop nutrient use efficiency. Evaluation of agroecosystem viability / sustainability with emphasis on soil, air and water quality ecosystem services in a changing climate. Examination of rooting dynamics, the root-soil interface and root/shoot ecophysiology and linkages to genetic basis of abiotic stress tolerance. Multivariate statistical approaches to analysis of soil health and environmental data sets. Analysis of scientific outputs (from science domains, research portfolios, etc.) for quality and inference space including relevance to smallholder farmers and usefulness in policy and management recommendation development.
