I am a research assistant and PhD student of English Linguistics at Heinrich Heine University Düsseldorf, Germany, and part of the research unit „Spoken Morphology“. My main work focuses on the interaction of morphology, phonology and phonetics in production, perception and comprehension. The working title of my dissertation is „Production, Perception, and Comprehension of Subphonemic Detail: Word-Final /s/ in English“. Further information is available here.

I am also interested in gender-fair language, especially in German, and the underlying representations of (non-)gender-fair language in particular. A related research project was currently launched by myself and four interdisciplinary collaborators. I co-signed a statement by German and international linguists on gender-fair language in December 2020.

I consider myself a supporter of transparency and integrity of research; I co-signed an open letter to protect academic whistleblowers and post-publication peer review.

My previous research mainly covered tonal alignment and compensatory vowel shortening. From 2017 to 2018 I also published more practical articles on IT in logopedics.
