Projects

1) How do species-specific traits such as biomass stoichiometry and growth rate shape the magnitude and temporal patterns of ecosystem-scale nutrient uptake? (This project is currently taking place with Jim Heffernan at Duke University, but might influence work at UNH) 

2) How do land use, precipitation patterns, and in-stream processing affect solute concentrations in the Lamprey River?

Effects of Nitrogen Saturation Experiments in Lowland Rainforest and Montane Cloud Forest of El Yunque Rainforest, Puerto Rico. 

Currently serving as the Managing Director for Pure Home Water, a non-profit company dedicated to providing affordable safe home water filtration and storage solutions to rural households in the Northern Region of Ghana.   Pure Home Water manufactures clay filters which can remove up to 99.9% of bacteria and protozoa water borne diseases from available public water supplies, typically including watering holes and dugouts, but also municipally piped drinking water.
