Focus areas
- Morphological forensic image comparison as a core field in court-related administrative offence and criminal proceedings
- Forensic age estimation at legally relevant age thresholds
- Morphological ageing of the human face and age-related feature changes
- 3D quantification of human morphological structures and standardised comparison images
These focal areas connect practical expert work with scientific activity. They also explain why publications, casework, and methodological contributions on the website are closely related to one another.
Verifiable reference points
- Expert witness practice since 2002
- Independent office in Berlin since 2006
- AGIB membership as a scientific expert since 2008
- Annual AGFAD certification since 2009
- Own specialist work on forensic image comparison, age estimation, and morphological ageing
These points are intended to make it understandable on what professional and temporal basis the practical work rests.
For an initial enquiry, the type of proceedings, the evidential question, and the current state of the material are sufficient. From this it can usually already be derived whether a preliminary review, technical visualisation, or a more extensive expert examination is appropriate.
Professional standards and the role of the expert witness
Morphological identity opinions require specific expertise, practical experience, and methodological care. The work does not consist in mere recognition or an overall visual impression. It requires a structured analysis of individual morphological features, an examination of their comparability within the material of the case, and a traceable classification of similarities, differences, and uncertainties.
The expert witness acts independently and impartially. He is bound to the evidential question, but also states openly when the submitted material does not support a reliable assessment or when further comparison options would be professionally useful. Information on qualifications, judicial practice, professional affiliations, and publications therefore serves not only information, but also transparency of expert work.
