Research Interests



     CLIMATE CHANGE: Greenhouse gas exchange processes in aquatic and soil environments

     WATER QUALITY: Transport and fate of reactive nitrogen in agricultural watersheds

     LAND USE CHANGE: Changes in the storage and stability of carbon and nitrogen in agricultural and forest soils

  


Environmental Sciences Laboratory

     

Lab is equiped to analyze gases, soils, and water using an aray of advanced analytical instruments (Varian GC450; AAS. Shimazu TOC; Dionex LIC). The investigation of stable isotopes as tools for understanding biogeochemical processes are frequently incorporated into the research projects we undertake (Nu-Instruments, GV Instruments IRMS).

Graduate Opportunities



Interested students should contact me directly to inquire about opportunities for graduate work.  There is an active MSc program in Earth Sciences at StFX. I supervise PhD students through my role as an Adjunct at Dalhousie University.
