Tim Randle graduated in 1985 with BSc(Hons) in Combined Sciences, specialising in Mathematics & Statistics and Life Sciences. He joined the Forestry Commission Research Division in 1986 as a modeller in the (then) Statistics and Computing Branch.

Current role

Research Scientist

Process modelling, developing models, which encompass the critical biological aspects of forest growth and impacts thereon, determining the relevant processes and their spatial and temporal scales. He has worked on a number of EU projects, for example LTEEF, ECOCRAFT, MEFYQUE.

Current programmes

Modelling and forecasting timber yield and quality in Europe (MEFYQUE)

Research areas

  • Process modelling of forest ecosystem dynamics and sustainability
  • Modelling forest growth and yield
  • Environmental and climate change
  • Modelling impacts
