Specialty：Nutrients in Soil and Water in human dominated ecosystems
Research. My research focuses on carbon and nutrient dynamics in urban and rural soil, runoff and surface water. I am a PI on the Scotts Company/Texas A & M (24 plot) runoff research facility where I have examined runoff carbon and nutrient concentrations and exports from warm-season turfgrass under fertilization, wetting agent and deficit irrigation treatments. In 2018 the plots were changed to alternative urban landscapes and this research is on-going. Soil sodicity of urban soils and its potential to impact on anion release and runoff has been examined in several cities (Chicago IL, Frederick MD, and Bryan/College Station and Galveston, TX)
Past work has investigated extractable soil nutrients in Texas and Ghana under tillage and cropping treatments; and iron and zinc in sorghum in Mali, and soils and water in Bangladesh, India and Iran. The investigation of carbon and nutrients released from decomposing mammals (mainly humans) with a view to estimating post-mortem interval is a relatively new field; decomposing mammals introduce another source of carbon and nutrients into the soil environment which is under researched. An expansion of this forensic research has been the development of use of UV-Vis-NIR spectroscopy with statistical models for trace soil evidence for a) determining percent similarity of soils and b) post-mortem interval prediction.
Teaching. I am currently responsible for teaching (or co-teaching) Watersheds and Water Quality Management (SCSC 458/658), Soil, Plant Water Relations (SCSC 309) each Spring. My Fall classes include Forensic Science (SCSC/FIVS 401) and the team taught graduate level course in Analysis of Environmental Systems (SCSC 618).
