Additional functions:
I am the co-leader of a work package entitled 'Interactions between acidification and climate change' as part of a EU funded project EUROLIMPACS. I also contribute to two DEFRA funded programs on critical loads/dynamic modelling and eutrophication and acidification in upland ecosystems.

Specialties of Rachel Helliwell:
I have worked as a biogeochemical modeller for the past 10 years focusing on the effects of atmospheric deposition, land management and climate change on acidification and nutrient cycling in upland ecosystems. In addition I am developing an up-scaling methodology to determine stream carbon and nitrogen concentrations from plot scale measurements of nutrients in soil, soil water, and vegetation and through analysis of hydrological pathways.
