Kale is a specialist in British and imperial history, and has published numerous works on the Indian indenture system. In a 2002 review of The Oxford History of the British Empire in Social History, she criticized the series as "a disturbingly revisionist project that seeks to neutralize ... the massive political and military brutality and repression" of the empire.[4]
