I continue work on several major projects involving RBG Kew, including the Angiosperm Phylogeny Group classification of plants, orchid evolution and classification and polyploidy and epigenetics and their role in angiosperm evolution.

Current projects:

Advantages of polyploidy: a case study in Nicotiana (Solanaceae)
Chromosome number change and life history strategies in angiosperms: a case study in Nicotiana sect. Suaveolentes (Solanaceae)
Phylogenetics and evolution of Orchidaceae
