I am Associate Professor at the University of Turin, Italy, and consultant for Forensic Toxicology at the Centro Regionale Antidoping e di Tossicologia “A. Bertinaria”. The laboratory received ISO 17025 accreditation in 2009 and performs over 300000 tests per year for road and workplace drug testing, driving re-licensing and drug abuse history. My research activity focuses on hair analysis, with close attention to new psychoactive substances (NPS), alcohol biomarkers and drug-facilitated crimes (DFC). I am regularly appointed as expert by the prosecutors or counsels in Italy to provide chemical analysis and assessment within complex judicial cases. I am now President of EWDTS and member of TIAFT, SoHT, SOFT, GTFI and SITOX. I co-edited a book about Hair Analysis in Clinical and Forensic Toxicology and authored or co-authored several peer-reviewed journal articles and several plenary lectures at national and international scientific meetings.
