Daniel joined the Science History Institute in August 2019 as a research fellow and the director of the Center for Historical Research. He specializes in the history of European physical science from the 19th century onward, especially in France and Britain, with a particular focus on the intellectual and sociocultural origins of the physics discipline and the longue-durée development of measurement, quantification, and mathematical representation. His work is characterized by a close study of scientific practice and content in relation to both knowledge exchange between different epistemic communities and the different forms of cultural and technological legitimization of that knowledge. Particularly through the institutional provision for science, he addresses these interactions in the context of government, industry, and society on local and national scales and in comparative international context. Daniel has formerly held research fellowships at RWTH Aachen University in Germany, the University of Cambridge, Harvard University, and the Science Museum, London.
