Martina Trognitz

+43 (1) 51581 – 2210


... studied Computational Linguistics and Classical Archaeology at the University of Heidelberg and is currently working on a PhD thesis on the ‘Computer-Based Analysis of Multi-Sided Minoan and Mycenean Seals’ which involves applying machine learning, clustering and social network analysis to an archaeological research question. At the ACDH-CH, Martina is part of the research unit DH Research&Infrastructure. Before her time at the ACDH-CH, Martina was employed at the German Archaeological Institute (DAI) where she was involved in the project IANUS to build a digital archive for the archaeologies in Germany and developed the IT guidelines IT-Empfehlungen für den nachhaltigen Umgang mit digitalen Daten in den Altertumswissenschaften. In 2017 Martina joined the team behind ARCHE at the ACDH-CH, which she is currently leading with Seta Štuhec.

Martina has accumulated over 10 years of experience in the fields of long-term preservation and data management, including a coverage of data formats suitable for long-term preservation, data management & planning for data management, FAIR data, metadata and metadata schemas, and controlled vocabularies. As a former fellow of the Open Science Fellows Program of Wikimedia Deutschland, Martina is an advocate for Open Science in all its facets.

Current research interests include the application of statistical and machine learning methods in Archaeology, Wikidata, network analysis, and Linked Open Data. Additionally, she is interested in everything involving photography and 3D, including RTI photography, spherical panoramas, photogrammetry and 3D scanning.
