Since 2016 I am responsible for Forensic Phonetics in Marburg regarding curriculum, research and casework.
Since 2010 I am a senior scientist/lecturer in phonetics at the University of Marburg in Germany. My main research interests focus on the area of forensic and perceptive phonetics. Other academic posts include Senior Research Associate at the University of Cambridge, Lecturer at City University in London and Guest-Lecturer at the University of Cambridge.
In addition to my work as a lecturer/researcher at the University of Marburg, I actively participate in training programs for police/justice departments and educational institutions (Selm-Bork: Hessen LKA Fortbildungsgruppe, Münster: Deutsche Hochschule der Polizei, Wiesbaden: HLKA Beratergruppe).
Since 2007, I provide consultancy for developing forensic laboratories as a forensic expert for the European Commission.
I have undertaken forensic investigations since 1994, for both prosecution and defense. Currently, I am leading a forensic phonetics team in Marburg conducting forensic analyses in civil and in criminal cases for different police forces in Germany. In the past, I have provided voice analysis services for a number of UK institutes/forces like the Forensic Science Service, Metropolitan Police and Liverpool Police and assisted the Dutch police.
I hold a PhD in linguistics from the University of Florida, an M.Phil. in Computer Speech and Language Processing from the University of Cambridge and a BSc. in Computational Linguistics from the University of Groningen.
Native speaker of Frisian (West-Frisian: Wâldfrysk variety) and Dutch. Fluent in English and German.
