Julia Sánchez-Dorado is a Humboldt Postdoctoral Fellow at the Technical University of Berlin, Institute of Philosophy (2020–22). Before that, she completed a PhD in History and Philosophy of Science at University College London (UCL), and a MA in Philosophy of Science at UNAM (Mexico). Her research interests lie in scientific and artistic representation, modelling practices, creativity, and the formation of agreements and standards in scientific communities. Her doctoral thesis, entitled “Scientific Representation in Practice: Models and Creative Similarity” (2019), examines how scientists make model-target comparisons during the design, construction, and calibration of their models, especially in the engineering science, in order to understand the importance of "similarity judgments" in the production of fruitful representations of natural phenomena.Julia’s project at the MPIWG (March–August 2020) was part of the larger project in digital humanities Measuring the Earth (Dept. III). Here she looked at the production of geodetical maps in the nineteenth and early twentieth century, making use of the archival materials of the “Digital Repository for the History of Modern Geodesy.”
