Céline (born in 1978) graduated from the University of Lausanne (UNIL), Switzerland, with a MSc in Forensic Science in 2000, after one Erasmus exchange year at the University of Strathclyde in Glasgow, Scotland (1998-1999).
The same year, she received the UNIL Forensic Science Alumni Award for three projects she carried out during her studies on gunshot residues, cannabis profiling and modelling of fiber transfer. She moved to Germany to pursue a PhD research project at the Institute of Inorganic and Analytical Chemistry of the University of Giessen under the supervision of Prof. Spengler and in collaboration with the Bundeskriminalamt (Wiesbaden). This research required the development of analytical techniques as well as interpretation models in a forensic science perspective. She received her PhD degree (summa cum laude) in 2005 on the subject: “Mass spectrometric investigation of the aging processes of ballpoint ink for the examination of questioned documents”. Her career took her back to the UNIL to work under the supervision of Prof. Pierre Esseiva and Prof. Pierre Margot on a European project of the 6th framework programme on the profiling of amphetamine type stimulants (2004-2005). In 2005, she was hired as an assistant lecturer and started several pilot projects on forensic dating issues which resulted in a Swiss National Science Foundation Professorship obtained in 2010 (still on-going). This project, supported by the UNIL, allowed her to fund three PhD research on fingermark, gunshot residue and ink dating. In 2012, Céline additionally received an educational grant to develop problem-based-learning in a new course on the theme of time issues in forensic science. During those years, she also participated to several international caseworks on ink dating and published many scientific articles in 3 languages (English, French and German) in collaboration with internationally renowned scientists in different forensic science fields (see selected key references below among about 30 publications; full up-dated list available on https://applicationspub.unil.ch/interpub/noauth/php/Un/UnPers.php?PerNum=26001&LanCode=37&menu=pub).
