As of September 2017, I have been collaborating in the impresso project. impresso stands for Integrated Monitoring of Historical Press Corpora. During a project phase of three years, which is financed by a SNSF Sinergia grant, the DHLAB at the EPFL, the C2DH at the University of Luxembourg, and our department will work on text mining of historical newspapers.

My main contribution to this undertaking was the lexical semantic indexing of texts and topic modeling of historical newspaper articles. 

In January 2021, I joined the Bullinger Digital project, which is dedicated to the digitalisation of the correspondence by Swiss reformer Heinrich Bullinger. The project's aim is to apply Handwritten Text Recognition (HTR) to about 3,000 of the over 12,000 letters Bullinger has written and received from many colleagues of his time from all over Europe. The project is kindly funded by the Hasler Foundation, among others, and also involves a partnership with Andreas Fischer from the Department of Informatics at the University of Fribourg and Tobias Hodel from the Digital Humanities group at the University of Bern.

Right now I am ...

... preparing my dissertation for publication.

... starting a collaboration with Locomot GmbH from Chur for an Innovation Cheque project to make photo archives more accessible.

... starting a collaboration with the Chair of Systems Desgin at ETH and the Heidelberger Akademie der Wissenschaften to track the spread of ideas in correspondence data during the Reformation.

... starting a collaboration with Patrick J. Burns from NYU about Latin language models.
