Vita

I am the team lead for Data Science Methods in the Department Computational Social Science at GESIS in Cologne and a junior professor for Responsible Data Science and Machine Learning at the Heinrich-Heine University Düsseldorf.

The team

The Data Science Methods team contributes to the GESIS infrastructure for CSS research by developing novel methods and making them available, documented, and accessible through the GESIS services. We focus on fostering the interaction between Natural Language Processing and Social Science by developing  solutions that allow for the integration of multiple information sources (e.g., different textual sources for the same debate; socio-demographic features of speakers and audiences) and address recent challenges in NLP (modeling subjective phenomena; low-resource scenarios; identifying and mitigating bias).

Our team tackles research questions at the interface between computational argumentation and computational social science and target political communication from a very broad perspective involving different types of actors (citizens, politicians, parties) and discourse contexts (e.g., online discussions vs. newspapers). From a methodological perspective, at the core of the team's research agenda is the challenge of learning from disagreements, as machine learning approaches which rely on gold standards which average annotators’ perspectives are particularly unsuitable for the highly subjective phenomena tackled in CSS research (e.g., persuasion in online discussions; harmful communication; polarization).

Service

The Data Science Methods team contributes to multiple services: the Methods Hub, the GESIS Guides to Digital Behavioral Data , and the GESIS Consulting on Digital Behavioral Data

Forschung

I am a computational linguist who loves applying NLP in interdisciplinary settings, with a strong focus on Social and Political Science (i.e., supporting decision making in forums with NLP; capturing the dynamics of political debates based on newspaper reports). In my research, further domains of interest for the application of NLP methods are cognitive modeling (i.e., prediction of speakers' behavior in psycholinguistic experiments with corpus-based models) and linguistics (i.e., lexical semantics).

Until December 2024, I have been a group leader at the Institute for Natural Language Processing (IMS) at the University of Stuttgart, where I have worked since the end of 2015. I lead the independent research group E-DELIB, funded by the German Ministry for Education and Research: we worked at the intersection of NLP, political science and decision making to develop automatic tools to support (digital) direct democracy. I hold a PhD in Cognitive Science from the University of Osnabrück, a MA in Theoretical and Applied Linguistics and a BA in Digital Humanities from the University of Pisa.
