Themes that animate my recent work include:

• Scientific (in)capacity in Africa as a lived social and material reality, and in relation to global health inequalities
• The afterlives of scientific materiality and labour in settings of economic uncertainty
• Civic subjectivities – pertaining to duty, public service and entitlement – in relation to scientific expertise in colonial and postcolonial Africa.
• The role of science (and its absence) in the unprotection – that is, the active production or preservation of gaps in protection – of health and, more broadly, of livelihoods and environments, particularly from toxic exposures.
