Dr. Abdallah has held numerous administrative and media positions at the Lebanese University, as well as at research centres and civil society organisations including the Development Studies Forum, the Lebanese Women Researchers Association, and the Islamic Cultural Centre. She participated in founding many faculties of information and communication, media and communication departments, and graduate institutes in Lebanon and the Arab world. In 2014, Dr. Abdallah founded the Arab Association for Scientific Research and Communication Sciences, headquartered in Lebanon, which has branches in most Arab countries and engages in numerous scientific research activities. She also established the journal al-Itisal wa at-Tanmiya [Communication and Development], which has published 28 issues so far. She contributed to the preparation and editing of multiple collective books, including al-Fikr al-Itisali [Communication Thought] (2018) and al-Mustalah fi ‘Uloom al-Itisal [Terminology in Communication Sciences] (2020). D.r Abdallah published her first book al-Itisal fi ‘Asr al-‘Awlama [Communication in the Age of Globalisation] in 1989 and was among the pioneers interested in the dimensions and impacts of modern technology on global societies, especially in the Arab world. Her second book, At-Talfizyon wa Tahadiyat at-Tiqaniyat al-Jadeeda fi al-‘Alam al-‘Arabi, focused on television and the challenges of new technologies in the Arab world. She has published many specialised scientific books, articles and research papers addressing the challenges and issues of modern technology. Dr. Abdallah also focused on the repercussions of technology on the academic, scientific and research fields of media and communication. She authored several books dealing with media and communication sciences and the theoretical and methodological problems of scientific research in the humanities and social sciences in general, and media and communication sciences in particular. She also paid special attention to the problematics of concepts and terminology. Working with a group of researchers, she helped unify research and media terms, resulting in the publication of Ma’jam Mustalahat al-I’lam wa al-Itisal [The Glossary of Media and Communication Terms] (2014). In addition, Dr. Abdallah worked to develop a theory reflecting Arab specificity and, in 2016, published a work proposing the theory of community participation in communication in the Arab world. In her book, Matahet al-Tawasul al-Ijtima’i fi al-Fada’ al-‘Am [The Maze of Social Communication in the Public Sphere], she offers a philosophical approach to social communication in the Arab region. This represents a research effort resulting from the work of the research team at the Arab Association for Scientific Research and Communication Sciences, as well as from the results of a recent survey study on social media usage during the COVID-19 crisis, which revealed the particular ambiguity of communication during times of crisis.
