Subject

I am a computational linguist with a strong interest in the applications of compuational semantics in interdisciplinary settings. My domains of interest are Political Science (i.e., supporting decision making in forums with NLP; capturing the dynamics of political debates based on newspaper reports), cognitive modeling (i.e., prediction of priming or and free associations) and theoretical linguistics (i.e., semantics of morphological derivation). My interest in NLP, however, is not restricted to specific applications; in the course of my PhD project, I have developed a more general, methodological interest on the identification of robust evaluation strategies which ensure a better understanding of the behavior of the parameters involved in the extraction/manipulation of corpus-based representations.

Starting from October 2020, I lead the independent reasearch group E-DELIB, funded by the German Ministry for Educationa nd Research: we are a team of four, and we work at the intersection of NLP, political science and decision making to develop automatic tools to support (digital) direct democracy. If you want to know more, have a look at the project site! I am a member of the Theoretical Computational Linguistics and Foundations of Computational Linguistics groups at the Institute for Natural Language Processing (IMS) at the University of Stuttgart.

Previously, I have worked  in the MARDY project, which brings together Computational Linguistics, Machine Learning and Political Science to model key aspects of the argumentation dynamics in policy debates. Before that, I have worked in the SFB 732 project B9 - Distributional Characterization of Derivation. From October 2014 to September 2015, I have been a member of the Corpus Linguistics Group at the Friderich-Alexander University of Erlangen-Nürnberg. From October 2013 to September 2014 I have been a visiting student at the IMS Stuttgart, where I was part of the Integrated Graduate School of the SFB 732 Incremental Specification in Context and a member of the Distributional Approaches to Semantic Relatedness research group.

My PhD in Cognitive Science, "Parameters, interactions, and model selection in distributional semantics" (University of Osnabrueck) has been supervised by Prof. Stefan Evert (FAU Erlangen-Nürnberg). I hold a BA in Digital Humanities and an MA in Theoretical and Applied Linguistics from the University of Pisa.
