Following several postdoctoral posts in the Botany Dept at Edinburgh University and in the Scottish Agricultural College, Joan joined Forest Research in 1991.

Current role

Programme Group Manager

  1. Programme Group Manager for Gene, Species and Habitat Conservation Programme
  2. Deputy Head of Centre for Centre for Ecosystems, Society and Biosecurity

Joan’s research interests within the Genetic Conservation Project include the following topics; assessment of adaptive traits in provenance trials of native tree species, distribution of intraspecific genetic diversity, geneflow between populations. She also maintains an interest in Molecular Tree Breeding and in the application of molecular marker technology in ecological and pest and disease research.

She has been involved in several large EU funded projects such as FAIROAK, EUROPOP, OAKFLOW, NOVELTREE and PROCOGEN. She was also a partner in the DEFRA funded LWEC project GRIPP and is currently a partner in the Phase II LWEC project PROTREE.

She has been an active research collaborator and has worked with staff in the following British organisations: the James Hutton Institute, Centre for Ecology & Hydrology, University of Edinburgh, Southampton University, York University, Bristol University, RSPB, East Malling Research.  She also has a network of European collaborators through her active participation in EUFORGEN and EU Cost actions. She has supervisory responsibility for several PhD students and is a member of the UK National Tree Seed Project Advisory Group.
