Mag. Dr. Katharina Korecky-Kröll is a linguist with a focus on digital linguistics, psycholinguistics and sociolinguistics. Her main area of research is German in Austria on the basis of spoken and written corpora. She is particularly interested in linguistic variation, especially in areal-horizontal, social-vertical, inter- and intra-individual variation of German morphology and pragmatics. She received her PhD at the University of Vienna in 2012. After postdoc positions at the Comparative Psycholinguistics Research and the ACDH-CH (formerly ICLTT and ACDH) of the Austrian Academy of Sciences, she is currently a postdoc researcher in the SFB German in Austria (DiÖ): Variation - Contact - Perception (FWF F60) at the Department of German Studies of the University of Vienna. Her main work in the Comparative Psycholinguistics Research Group consists in comparing Austrian German child language acquisition data and adult dialect-standard variation data by using different experimental and naturalistic methods.

Her dissertation investigates the impact of siblings and peers on language acquisition and is titled: "The impact of siblings vs. peers on the German language acquisition of Viennese bilingual children". Fischer's interest in the field of sibling research started growing while working as a transcriber for the INPUT project. In November 2020 she started working on her PhD project and joined the research group with a position at the Department of Linguistics.
