Forensic science or sciences? The recognition as an independent science and redefinition of expert practices based on transdisciplinary

Forensic science explores scientific knowledge to clarify legal and legal issues. Since I started in this area of knowledge in mid-2007, my priority has been to create a centre of reference and excellence that would advance forensic science, an area sometimes based on self-taught practices. Along this pathway, I always considered that we were dealing with an articulated set of "Forensic Sciences" and not with a single "Forensic Science", but I was, at least partially, wrong! This work discusses the competencies of the different forensic subspecialties, seeking to be the starting point for reformulating forensic teaching, research, and public and private forensic activity. It also highlights the concern of offering a certain level of professionalization to forensic science. For this reflection, it was important to follow a path that had its foundations in the study of the historical roots of forensic science, namely the first Portuguese forensic case, to study the revolutionary scientific contribution triggered by the "CSI effect", to understand in depth the competencies of each of the forensic subspecialties and bring this knowledge to specialized pre- and postgraduate training, to promote innovation through peer review of empirical forensic practices to increase the scientific evidence, the development of certification mechanisms for forensic experts and their respective code of ethics, and to open the doors for artificial intelligence to assist the courts and the opportunity that forensic science represents in the development of other areas of health sciences, life, and social behaviour. Thus, it was born, very unconsciously, a scientific project for the transdisciplinary reformulation of forensic activity, but over time, it allowed me to realize that we can have specialists trained in all its dimensions and plenitude. The pillars for the modernization of this science and, ultimately, the law, which, together with education and health, are the three main pillars of society. Not punishing innocent people, leaving criminals unharmed through scientific evidence, seeking justice, and repairing the damage is the supreme spirit of Forensic Science. Our One Forensics model is now being considered to be implemented by other countries.
