Klaus Thoden is a Visiting Consultant at the Max Planck Institute for the History of Science in Berlin. He received his Magister Artium (MA) in German language and linguistics from the Humboldt University, Berlin in 2008.

Klaus is the technical coordinator of Edition Open Access, a publishing platform for open access publications. During a two-year-project (2018-2019), he headed a small team that fundamentally remodeled the whole publication infrastructure (funded by the Federal Ministry of Education and Research, grant number 16OA061).

At the MPIWG, he has also been involved in developing an infrastructure for digitizing sources for the ECHO environment and between 2012 and 2017 was involved in national and international infrastructure projects (DM2E, TextGrid, DARIAH-DE). The focus of his research is the influence of computers and the internet on the way scholars perform their work. This includes usability studies, modeling research activities (e.g., TaDiRAH, Scholarly Domain Model), impact studies (e.g., Impactomatrix), and most recently, research on the publication process in the humanities.

Klaus is committed to open science and open-source software. Code he has authored or co-authored can be found at molgen github, gwdg gitlab, and microsoft github.
