Interested in evolution at the DNA sequence level. Specifically the consequences of polyploidy in Nicotiana and plant DNA barcoding.

Reconstructing the phylogenetic relationships of plant species based on DNA sequence data. Involved in many collaborative projects in Kew’s Molecular Systematics Laboratory. Special interest in understanding the genetic consequences of polyploidy in Nicotiana over different timeframes. Investigate processes such as reticulate evolution, allopolyploid speciation, homoploid hybrid speciation, recombination and diploidisation. Recently became involved in the large international collaborative effort to test and select suitable regions for the DNA barcoding of land plants. Also work closely with specialists in Kew’s Herbarium collaborating on projects for specific plant families (recently focused on Arecaceae and Meliaceae).
