Clare's research has focused mainly on the arts of the Meiji era (1868–1912), in particular Meiji artistic textiles, the work of the versatile potter Miyagawa Kōzan (1842–1916) and artistic exchange between Japan, Europe and Asia in the late 19th century.
She also has an interest in Japanese prints, from surimono privately published poetry prints to the landscapes of Utagawa Hiroshige and the development of Japanese printmaking since the late nineteenth century.
