Image en tons neutres et minimalistes : un paysage de montagnes superposées dans des nuances de gris et de beige. Une brume flotte, créant une atmosphère mystérieuse. Au centre de l’image, un cercle noir au pinceau de style ensō japonais attire le regard. L’ensemble évoque la sérénité et la profondeur.

Profile Madeleine Rossi


Journalist (professional registration)
Consultant
Translator

Independent investigative journalist, specialized in Italian mafias and, in particular, their influence in Switzerland. I gained solid field experience in Italy and have published extensively on this subject.

I am the author of a pioneering report on the presence of mafias in Switzerland (2019) and of the book La Mafia en Suisse (Attinger Editions, 2021 – expanded edition in 2023).

I also speak at public events and act as a consultant for various stakeholders in both the public and private sectors.

The demands of investigative work and research find a natural extension in my other professional activity: translation and related linguistic services. This complementary discipline calls for strong analytical skills, precision, and rigor.


Investigation & Media Content

Field investigations, in-depth articles, long-form features, interviews, radio/photo reports, and collaborations with various media outlets: Swissinfo, La Liberté, Lausanne-Cités, Le Matin Dimanche, Radio Télévision Suisse (RTS), among others.

My approach is grounded in accuracy, critical analysis, and systematic source verification. I also rely on a cross-border network of contacts in the judicial, police, banking, media, and scientific sectors.

Public Speaking & Consulting

Advice and support on issues related to Italian mafias—their sociology, culture, methods, and transnational presence.

Public and corporate speaking engagements, as well as contributions to institutional forums, on general or specific topics: history of mafia presence, indicators of infiltration risk, detection of weak signals, prevention and awareness tools.

Expert input for professional projects, reports (public and private sectors), master’s theses, and high-school research papers.

Translation & Language Services

Translation (EN>FR and IT>FR), proofreading, editing, transcreation, transcription, linguistic validation, consecutive interpreting (IT<->FR).

Areas of specialization: medical/health, food safety, disaster risk financing & management, climate insurance, criminal/administrative law, social sciences, history, religions, literature.


In addition to various radio and television appearances (RTS, Radio-Chablais, France Culture, RCFM), I have had the opportunity to share my experience and fieldwork during engagements and exchanges with a variety of audiences. Among these are:

  • Study trip to Palermo organized by the University of Zurich Chaplaincy (AKI), April 2025
  • Lausanne Méditerranées Festival, “Regards croisés sur la mafia” alongside psychoanalyst Nino Rizzo, October 2024
  • Conference “Mafia senza frontiere” with Italian journalist Lucio Musolino, organized by the Regional Council of Aosta Valley, July 2024
  • Conference “La lotta al crimine organizzato in Svizzera: ieri, oggi... e domani” alongside former Swiss prosecutor Paolo Bernasconi, organized by the University of Lucerne, May 2022
  • Conference “Mafia & Co.” with journalist and writer Sampiero Sanguinetti, organized by the association U Svegliu Calvese (Calvi), November 2018
  • Annual conferences of the Italian anti-mafia foundation Antonino Caponnetto (Florence and San Marino, 2011-2017)
