Joelle Farchy, Professor of sciences of the information and the communication, is part of a legal University department of University Paris 1 Panthéon Sorbonne and of a research center in economy, discipline in which she began her course. The multi-disciplinary approach is a strong characteristic of her scientific activity. Collaborations of research were committed with researchers in information, communication, as well as legal experts and sociologists (reports and scientific papers in common, publishing coordination). Regarding the intellectual property, economics brought a cross perspective that seemed particularly fruitful. This multi-disciplinary approach is still in progress in the educational sphere. From an institutional point of view, this approach led her to participate first of all in the activities of the SFSIC (French company of information and communication sciences), then to the Editorial committee of a communication review (Hermes, published by the CNRS (national center for scientific research) and to the scientific Council of a legal review (Lamy, Immaterial’s right). Another strong characteristic of Joelle Farchy’s activities and researches in applied economics communication is that she work closely and positively with the academic advances and the professional world. Her role at the French Institute of communication (partnership INA - Paris1), at the upper Council of the literary and artistic property (meeting of several tens of culture and media professional representatives under the supervision of the Culture and Communication Ministry) or at the National Commission for Data Protection and Liberties (CNIL) illustrate this constant interaction. The creation in 2010 of the EMNS (School of the media and the digital of the Sorbonne), combining multidisciplinarity, teaching, studies and research, media professionals and academics, embodies a long-standing commitment.
