Weston's research has focussed on the theory and practice of phylogenetic analysis, and the broader uses to which phylogenetic theory may be applied. He has carried out phylogenetic analyses of groups in the Proteaceae, Fabaceae, Orchidaceae and Rutaceae families and used the results to test theories of historical biogeography, trait evolution and adaptation. At NSW he curates the Proteaceae, Faboideae (Fabaceae) and Orchidaceae. He has collected plants in Australia, New Zealand, New Caledonia, Chile, South Africa, Argentina and the U.K.
