Dr Wald's research interests lie across the fields of imperial, social and medical history. In particular, Dr Wald focusses on the nineteenth century in colonial India.
Dr Wald's past research explored the interlinked themes of the military, medicine and morality in early nineteenth century India. Her book, Vice in the Barracks: Military, Medicine and the Making of Colonial India looks at the ways in which concerns over ‘vice-driven’ health threats – such as venereal disease and drunkenness in the army dictated the colonial state’s policies.
Dr Wald's new project examines the role of medical knowledge networks across British India.
