Stuart joined Forest Research in 2003, where he specialises in applying DNA based techniques to tree breeding and ecological issues. He studied Zoology at Aberdeen University (1989-93), Biotechnology at the University of Abertay (1993-94) and received his PhD from Edinburgh University (1994-1998) for his thesis on the Population Structure of Linyphiid Spiders. Prior to joining FR, Stuart worked as a postdoctoral scientist at the Roslin Institute and at the Scottish Agricultural College.
Responsibilities include Project Leader for Forest Reproductive Material and managing the Molecular Biology Laboratory.
Also manage a commercial molecular service to provide solutions to ecological topics such as DNA fingerprinting of black poplar clones and identification of field collected mammal droppings.
- Monitoring presence of bird and mammal species using molecular markers designed for use with faecal samples.
- Development and application of microsatellite DNA markers in Twinflower (Linnae borealis) and squirrel.
- Supporting Forest Reproductive Material (FRM) regulations for black poplar and aspen by identification of clones used in propagation.
- Genetic investigation of Pine-tree Lappet moth using mitochondrial sequence data and microsatellite markers.
Selection and testing of conifers
Responsible for development of Marker Assisted Selection program in Sitka spruce, including the generation of a Sitka genetic linkage map and QTL discovery for commercial traits of interest.
NovelTree EU project (2008-2012). An EU collaborative project
This project will mobilise and integrate European scientific research and resources on forest tree genetics to (i) develop genomic tools for plant breeding, efficient gene isolation, and optimised exploitation of genetic resources and (ii) demonstrate novel/improved methods to breed trees with improved quality and quantity parameters. This work will continue as a new EU funded project (PROCOGEN).
- Forest Research representative in EUFORGEN Forest Reproductive Material working group
- Memorandum of Understanding with Genome Canada consortium for partnership in Molecular Breeding
- Marker assisted selection in Sitka spruce
- Species identification using molecular markers
- Clone identification
- Population genetics
