Specializing in metabolomics, natural products chemistry, and plant biochemistry, Farag completed his PhD at Texas Tech University, USA, in 2003. In 2005, after spending time as a postdoctoral fellow at The Samuel Noble Foundation, USA, and the James Graham Brown Cancer Center, USA, he became assistant professor in 2005 at the Faculty of Pharmacy, Cairo University, Egypt. Since 2009, Farag has been working as a part time visiting professor at the Technical University of Munich, Germany, to participate in teaching plant metabolomics and chemomterics modelling for master students, and in 2009–2010 he held the Alexander von Humboldt fellowship in Germany. Farag now works full time as a professor at the American University in Cairo (AUC) where his research work focuses primarily around applying innovative biochemical technologies (metabolomics) to help answer complex biological questions in medicine, herbal drugs analysis and agriculture. For his highly cited publications of close to 5000 citations and an H index of 32, Farag was selected as a top researcher in the field of plant biology in Africa by the American society of plant biology, United States.
