Profile Summary

I am a linguist specialized in phonetics, with a research focus on speech production and perception in both healthy and clinical populations. My recent work has examined adaptation phenomena in speech perception, particularly their relationship with information quality. I also investigate the temporal organization of prosodic cues in Parkinson’s speech, with an emphasis on how patients acoustically encode intonation and prominence. My professional interests include teaching and postdoctoral research positions. I am especially interested in further developing my skills in data analysis, programming, machine learning, and neuroimaging, and I am therefore open to positions beyond traditional academic settings.
