I am a cognitive scientist with a focus on speech patterns of human language. My research interests centre around the question of how multidimensional, continuous aspects of speech can be related to discrete behavioural observations. I attempt to answer this question by investigating how communicative functions are phonetically encoded during speech production and how and when aspects of the speech signal are picked up during speech perception. Given the facts that speech transmission is tremendously noisy and rapidly unfolding in time, I believe we can advance our understanding of human speech only by triangulating in-depth behavioural evaluations of speech production and speech perception, neuroscientific methods, and computational modelling.

My past and current research endeavours include: productivity of lexical regularities, phonetic encoding and decoding of subphonemic cues, the interaction of segmental and suprasegmental aspects of speech, the intonational encoding of discourse functions in German, Bari Italian, and Tashlhiyt Berber. I am also particularly interested in the interaction between speech and aspects of cognition that are traditionally not associated with speech processing. Themes that I have worked on include: numerical processing and its interaction with spatial orientation, motor behavoiur in tremor patients and, most recently, the link between perception and motor behavoiur.
