Professor Ed Tipping, DSc

Research interests

I work on environmental chemistry, focusing on acidity, metals and natural organic matter in soils and waters, with an emphasis on modelling. Recent and current topics are:

• Cation-binding by natural organic matter – improvement of the WHAM chemical speciation model (Metals Industry)
• Dynamics and toxicity of mercury in soils (Defra)
• Soil and water carbon dynamics using natural-abundance 14C (NERC)
• Metal toxicity – mixture effects in the field (EA, Metals Industry)
• Coupling C and N soil turnover, in relation to N availability and leaching (Defra)

I hold a DSc from the University of Manchester, and I am a Visiting Professor at the University of Lancaster.
