Current research activities

Andy is head of the Analytical group at the Macaulay Land Use Research Institute and leads a team of over 20 staff with a remit to provide a suite of analyses to meet the needs of the Institute’s changing and dynamic research program with an emphasis on environmental research. The laboratories handle about 40k samples a year and have an annual turnover of close to ~£1 million. The group caters for a range of commercial clients from a variety of public and private sectors including the oil industry, local authorities and environmental consultants. The Group holds ISO 17025 accreditation for much of the work undertaken.

Andy research interests are concerned with the use of stable isotopes to study plant and soil interactions. He is currently involved in work to study below ground carbon transfers and the partitioning of soil surface CO2 efflux using stable isotopes; this involves colleagues in the US, Canada and New Zealand. Andy is a member of the American Geophysical Union, an Honorary Lecturer at the Robert Gordon University, Aberdeen and a member of the Royal Society of Chemistry (MRSC) and Chartered Chemist (CChem).
