After Numbers? Doing and Undoing Numbers

Numbers are ubiquitous. Their numberly guise makes numbers seem trustworthy. While mathematics offers formal rules, numbers in practice are shaped by social contexts. In practice, numbers are always socio-materially performed. A child learns counting on their fingers; in the supermarket, we engage in practical arithmetic – far removed from the formal mathematics taught in high school or university. I wonder: How are numbers enacted in everyday work practices, and in what ways are they destabilised or even undone? And what is inside numbers? What unfolds before they appear, behind their apparent precision, and beyond their immediate representation? In short: What happens before, behind, after numbers?

Data Practices and Digital Accountability

Expanding on my PhD work, I pursue the empirically grounded hypothesis that data is not something given but rather something made. Although the word "data" etymologically refers to what is given (from the Latin dare), in practice data is constructed. Data emerges as facts — factum in Latin, meaning "something done"—underscoring that the production of facts is an active, performative process. Fact-making is, indeed, a central concern in STS, where we scrutinize the processes behind what is taken as given. My research specifically examines how practices of preparing, configuring, and generating data are deeply entangled with efforts to render these practices transparent and accountable. In exploring digital accountability, I focus on how socio-technical infrastructures shape both the capacity to respond – what I term "response-abilities" – and the limitations imposed on such capacities.

Methods and Matters of STS

STS has a long history of scrutinising the methods and analytical infrastructures of other scientific fields. Despite its renowned reflexivity, STS has sometimes neglected to detail the material and semiotic practices through which it enacts analysis and produces data. STS is inherently political – not only in its discourses but also in its methods of data-making and the ways it documents its research. This work is committed to developing a methodographic genre – a systematic approach to detailing the practices and politics through which STS enacts its own research.

Energy Knowledges

Discourses of energy transition require knowing energy. As a social scientist, I am interested in how such knowledge is produced, resulting in an understanding of the specificities and politics of energy knowledges. Energy knowledge is shaped not only in the lifeworlds of consumers and customers but also in the workplaces of energy and environmental governance practitioners. Systematising energy knowledge is typically coupled to information infrastructures. Databases about energy generation and consumption are abundant. What data about energy does not get generated? What data is not processed or simply ignored? Who determines what counts as a kilowatt-hour?" Just as knowledge is structured by databases and infrastructures, it is also shaped by the landscapes that energy production consumes – what is recorded, and what is erased, both in data and in space. Yet, energy is also known from the outside – not just through structured knowledge systems like databases, but through the landscapes it transforms, as in the case of ongoing lignite mining. I explore how such places – consumed, devastated, and destroyed for energy generation – become objects of knowledge, at times ignored, and written into and out of histories.

Corporate Carbon

Global climate change solutions are often framed as dependent on shifts in industrial and economic relations. Production and service sectors must be decarbonised as we move away from the carbon economy. This project ethnographically examines how corporate carbon accounting – in one of the 50 largest companies on our damaged planet – renders visible the carbon intensity of a multinational’s operations. Positioned at the intersection of STS, environmental sociology, and organization studies, I analyze how carbon accounting enacts particular environments and identifies patterns of accounted-for environmental impacts that stabilize core financial interests, all while ensuring that environmental concerns remain peripheral to the corporation’s central operations. Internal externalities, indeed.

Environmental Management Studies

Environmental management and governance are widely promoted as key to achieving sustainable development. Universities now offer numerous programmes in environmental and resource management, alongside their governance. Traditionally, environmental management research has focused on evaluating existing management instruments, refining them, or proposing alternatives. In contrast, my research adopts a radically different approach by examining environmental management as a set of situated practices. I investigate not only the tools and techniques employed by environmental managers but also the everyday work practices – shaped by historical, geographical, and political contexts—that underpin ecological modernisation. Through ethnographic methods, I foreground the experiences of environmental managers, their instruments, and how these are actually used in practice. This approach contributes to critical environmental studies, human geography, environmental sociology, and an environmental or earthly STS.
