Nicola Moessner currently holds a position as a lecturer at the Department of Philosophy at the RWTH Aachen University, Germany. Between 2015 and 2016, she was a Junior Fellow at the Alfried Krupp Wissenschaftskolleg Greifswald, Germany. In the philosophy of science her main interests of research comprise, on the one hand, Ludwik Fleck's theory of social dynamics and infl uences on epistemic processes in science and, on the other, the epistemic status of visual representations in processes of scientifi c reasoning and communication. She edited (together with Alfred Nordmann) Reasoning in Measurement (2017) and (together with Dimitri Liebsch) Visualisierung und Erkenntnis - Bildverstehen und Bildverwenden in Natur- und Geisteswissenschaften (2012). Another area of her specialisation is social epistemology. In this context she worked on the epistemology of testimony and published Wissen aus dem Zeugnis anderer - der Sonderfall medialer Berichterstattung (2010).
