My research interests include prosody, especially intonation, and conversational behaviour, such as backchannels, filled pauses and turn-timing. I have focussed in the bulk of my recent work on investigating these dimensions of communication in the context of autism, but I also have an active and long-standing research interest in second (and first) language acquisition and non-native speech. More broadly, I am particularly interested in individual- and dyad-specific variability and enthusiastic about open science, data visualisation and Bayesian statistics.

My most recent work explores the interplay of visual and spoken signals in conversation, with a special focus on eye gaze, while also delving deeper into the role of response tokens and the production and perception of global intonation patterns (incl. the metrics of wiggliness and spaciousness). An overarching aim in my current and planned research is the alignment of insights from cross-cultural and cross-neurotype interactions.
