In 2018, he was elected to the United Nations Committee on the Rights of the Child.
A clinical and a forensic psychologist trained in Switzerland and in the USA, for many years his academic and professional activities have focused on children's rights, the protection of the child, in particular concerning sexual abuse, participation of the child in the civil and criminal legal system, and detention issues.
Still a practicing licensed psychotherapist and a court-appointed expert witness, he has also conducted clinical and training consultancies for a wide range of humanitarian organizations, both governmental and non-governmental.
Beyond the traditional "teach, research, publish or perish missions" required by a leading university, his vision of academic life is to branch out in the community at large as a science practitioner and educator.
