Tim joined what is now Forest Research in 1986, following his degree in Combined Sciences (specialising in Life Sciences and Mathematics and Statistics).  His modelling work usually follows the process model paradigm rather than statistical analysis.

Current role

Research Scientist
Tim gets involved in a number of projects as demand requires. More recent modelling work has focussed on the carbon balance of forests, helping to develop the sequestration lookup tables of the Woodland Carbon Code, and is currently working on a forest litter and soil-carbon model. He has participated in a number of national and international consortia projects and contracts.

Current projects

Forest resource assessment and modelling

  • Modelling to underpin forest carbon balance reporting, management and policy (Forest carbon balance modelling.)
    • Woodland Carbon Code
      Improving and revising lookup tables
      Account for operational emissions
  • Establish robust scientific basis for modelling carbon dynamics of non-tree forest carbon pools.
    • Soil Carbon Modelling
      Develop a model for organic carbon in soils and litter based on current science

Other affiliations and responsibilities

  • Co-Supervisor for PhD student (joint FR and University of Aberdeen)
  • Treasurer and Member of Branch Executive Council for Prospect (Forestry Commission Branch)
  • Health and Safety officer for Centre for Sustainable Forestry and Climate Change, Alice Holt
