Lama Mattar

Passionate about Nutrition, Lama pursued her BSc and MSc in nutritional sciences at the American University of Beirut, Lebanon. She followed her passion even further and achieved a PhD specialized in eating disorders and behaviors at University of Pierre & Marie-Curie in Paris, France (2011).
Lama believes that nutrition is the cornerstone of the medical therapy for many diseases. This belief in the therapeutic aspect of nutrition made her practice clinical dietetics in various specialized units in the USA, Switzerland, Lebanon and France. She gained a broadened experience by completing a post-doctoral project on cancer and malnutrition in hospitals.

Besides her clinical practice, Lama is passionate for teaching and research. She taught graduate and undergraduate nutrition courses at the American University of Beirut and is now Assistant Professor at the Lebanese American University. She was invited as guest speaker to several international conferences and publishes extensively in peer-reviewed journals. She got awarded from the French Ministry of Foreign and European Affairs an Excellence scholarship (2010) and from King’s College in London, a research Excellence fellowship (2012).
