My research focuses on the biodiversity and evolution of plants, particularly speciation, a primary generator of biodiversity. I work at the interface of population genetics and molecular systematics, studying adaptation, population divergence, hybridization, mating system evolution, reproductive isolation, speciation and the evolutionary history of Arctic, Alpine, Mediterranean and Temperate species.

One particular research interest concerns the genetic and evolutionary consequences of interspecific hybridization in the genus Senecio, especially the origins and evolution of three recently originated hybrid species and one stabilised introgressant. These are: (i) the homoploid hybrid species, Senecio squalidus (Oxford ragwort), (ii) the allohexaploid, Senecio cambrensis (Welsh groundsel), (iii) the allotetrapolid, Senecio eboracensis (York radiate groundsel), and (iv) the stabilised introgressant, Senecio vulgaris var. hibernicus (Radiate groundsel). All four originated in the UK during the last 300 years and are excellent models for the study of hybrid evolution.

Senecio Research Network

I collaborate internationally with many researchers. An ongoing long-term collaboration with Professor Jianquan Liu (Lanzhou and Sichuan Universities) on plant speciation in China has produced 28 research papers (since 2004).

Discovered a newly originated plant species in the British Isles. Front page news in ‘The Times’, and reported in most other national newspapers and on radio. Senecio eboracensis (York radiate groundsel) is one of only 6 plant species known to have originated worldwide within the last 250 years. It is now extinct in the wild but is maintained in cultivation for future research and reintroduction.

Published >200 research papers in a wide range of refereed journals and books, including Science, Nature Communications, Proceedings National Academy of Science USA, Molecular Plant, Trends in Ecology & Evolution, Philosophical Transactions of the Royal Society London B, Evolution, Heredity, J.
