I have been a field botanist for more than 20 years and started my scientific career with the MSc course in "Biodiversity and Taxonomy of Plants" at the Royal Botanic Garden Edinburgh/University of Edinburgh. I then worked at the Royal Botanic Gardens, Kew on the Rubiaceae World Checklist and on various aspects of Rubiaceae taxonomy. After the completion of this project I did a PhD at the University of Edinburgh investigating the evolutionary consequences of hybridisation between inbreeding and outcrossing plant taxa using Geum urbanum (Rosaceae) and G. rivale as study species.
Current research interests
- Conservation genetics of the British Flora
- Evolutionary consequences of hybridisation between plant taxa with different mating systems
- Effects of fragmentation on populations
- Plant speciation
