Jeg forsker på plantesystematikk og evolusjon, og har spesialisert meg spesielt på blomsterplanteslekten Erica (Ericaceae) og familien Annonaceae. Mitt kuratoransvar omfatter Arboretet som helhet, med fokus på våre forsknings- og bevaringssamlinger, særlig av Ericaceae og Rosaceae, og gjennom engasjement i nettverk som Global Conservation Consortia (GCC) i Botanic Gardens Conservation International, som jeg koordinerer GCC Erica for.
