Population & World History
Population is a 360-degree problem – a gripping challenge for world historians: fertility and mortality; food production and consumption; soil fertility and land-use; economy and ecology; energy and physiology; international relations and intimate relations; colonialism and development. Bashford’s model for bringing this all together is to consider population simultaneously as geo-politics, bio-politics, eco-politics and cosmo-politics.

New Earth Histories and Deep Time
New Earth Histories brings the history of geosciences and the history of select world cosmologies together. Founded at UNSW in 2017, this research program aims to produce a fresh and cosmopolitan history of environmental sciences, analysing the significance of geological time and multiple cosmologies for global modernity itself. Bashford explores the modern history of deep time – human, before human, and beyond human. With colleagues, she is researching the modern history of an ancient supercontinent, Gondwanaland.

Eugenics
Where did eugenics go? With this key question in hand, Bashford has explored a long history of eugenics, dispelling the idea that eugenics either vanished or went underground after World War II. She has tracked eugenics’ explicit transformation into social biology, into transhumanism, and into neo-liberal, choice-based assisted reproductive technologies. How and why did eugenics flourish amongst progressivists, modernists, reformers, and even key twentieth-century anti-racists and anti-colonials? Eugenics needs to be understood within 20th-century conceptions of “freedom” and “duty,” as much illiberal coercion.

Quarantine, Disease, and Border Control
Bashford’s earliest research unpacked a long history of global medico-legal border control, tracking the epidemiology, politics, law and culture of segregation, isolation, and quarantine. Four edited books – Contagion (2001), Isolation (2003)and Medicine at the Border (2006) and Quarantine (2016) – tackled the histories and geographies of biosecurity, all prehistories of a coronavirus world.

Immigration Law & Regulation
Working outwards from the history of quarantine law, Bashford has researched the related emergence of immigration restriction over the nineteenth and twentieth centuries, almost always involving health and disease regulations. Over this world history of increasingly rigid national border controls, she argues that the UK has been an important liberal outlier.
