Dr Annette RyanLaboratory Manager
My research background includes three years working in the Antarctic as a Meteorologist and Physicist, a PhD in Biosphere-Atmosphere Interactions, and six years working as a Senior Research Associate investigating plant responses to oxidative stress and how efficiently cereal crops use water and alter transpiration in response to changing atmospheric vapour pressure deficit. I now manage the Soils and Ecosystem Ecology Research Laboratory at Lancaster University, supporting the research of six Professors and Lecturers, and approximately 50 research staff and students. The group focuses upon plant-soil interactions, soil and ecosystem biogeochemistry, macronutrient cycles and greenhouse gas emissions. Facilities and techniques available include analysis of C, N and P, PLFA and enzyme assays, raw fibre analysis, plant and soil respiration, greenhouse gas analysis and soil density fractionation. The lab also has a range of field equipment including infra-red gas analysers, soil moisture meters and soil respiration and photosynthesis chambers. My interests lie in exploring new methodological techniques and analysis to enhance the capabilities of the research group.
