Dr Tan specialises in medieval Chinese literature and is interested in examining how a literary piece is formulated using a cross-disciplinary approach. Prior to joining HSUHK, she taught at the University of Wisconsin–Madison and The Chinese University of Hong Kong, where she obtained experience in teaching Chinese-related subjects, running language programs, and producing online learning courses; one funded by the Teaching Development Grant. She has also compiled bibliographies on Chinese studies for the Cambridge University Press and edited translations of Chinese classics for the Chinese University Press.
