Her research focuses on the methods and assumptions involved in the use of big data for discovery; the challenges involved in the extraction of knowledge from digital infrastructures, and the implications of choices in data curation for the outputs and uses of science and technology; the role of the open science movement within current landscapes of knowledge production, including concerns around inequality; and the status and history of experimental organisms as scientific models and data sources. She published widely in various disciplines, including philosophy, history, social studies of science, data science and biology; and is active in science policy, particularly as an adviser on Open Science implementation for the European Commission and the steering boards of various research data infrastructures.
