Research Forester: Researcher on Measurement Systems

Ewan is the leading scientist at Forest Research working on tree and timber measurement systems research. He draws on his forestry and wood science expertise to undertake systems analysis of forest management and wood supply chains, as part of life cycle assessment of forestry systems and wood products.

He is the principal point of contact and advisor for representatives of the forest industry, researchers and members of the public raising queries relating to forest, tree and timber measurement, methodologies and the practice of forest mensuration, including systems analysis of wood supply chains.

Ewan is also the programme manager for the Resource Assessment and Sector Monitoring theme of the Science and innovation strategy for forestry in Great Britain

Ewan studied Forestry at Aberdeen University between 1994 – 2001, completing a first degree and an MSc in Forestry and Wood Science by research. He then worked for the Forestry Contracting Association (FCA), initially as a research assistant whilst completing his MSc and then as a researcher dealing mainly with timber transport and woodfuel supply chain issues. He joined Forest Research in 2002.
