Research directions
Research in the area of microtraces and unusual traces
Research examples:
- Fiber transfer and background in the respiratory tract in cases of smoothering
- Transfer and background of fibers on knives in cases of textile damage
- Transfer, persistence and background of condom residues in cases of sexual assault
- Variability study on automotive paints (same car make and colour)
- Study of secondary fiber transfer and its contribution to case evaluation
Interpretation of the findings at the activity level
Estimation of occurrence with population studies. Market studies to infer on possible sources
Interpretation of the findings at the activity level
Study of the different factors: background, transfer and persistence. Modelization of the interaction of these parameters using design of experiments (DoE). Bayesian approach and Bayesnet.
Analytical chemistry (spectroscopy, PyGCMS)
Application of new techniques and methodologies (instrumental set-up, validation, calibration), discriminating power, evidential value, batch variability.
Statistical data treatments (analytical results)
Application of various techniques for sample grouping and discrimination (PCA, LDA, multiblock techniques). Continuous LR on spectral data. Databases.
