Sharon joined the Royal Horticultural Society in late 2006 as International Narcissus and Dahlia Registrar. In 2010 she also became the Conifer Registrar. The three groups generate around 300-350 new names a year, with research into areas such as classification and older names also being a large part of her work. She is Secretary to the Advisory Sub-Committee on Narcissus Classification.
Sharon previously spent four and a half years working at RBG Kew as the Assistant Scientific Officer for the Temperate Section of the Herbarium. She helped to curate material for about 100 plant families and participated in a trip to Kamchatka (2003) in search of herbarium specimens and to New Zealand (2006) collecting herbarium specimens and seeds; she also taught on the Herbarium techniques course in Istanbul in 2006.
