About

I’m a Senior Research SDE at Microsoft Research. My main focus areas are Natural Language Processing (NLP), Conversational Systems and Cloud based solutions. I joined Microsoft Advanced Technology Lab in Cairo (ATL-Cairo) in September 2011 and worked in the R&D of multiple NLP tasks such as Unsupervised Named Entity Recognition, Open Information Extraction, Language Understanding, and lately Conversational Systems. Before I join Microsoft, I worked in the R&D of an enterprise Arabic-English Machine Translation system for around 4 years at Sakhr Software. My MSc was in the field of Ontology based NLP, particularly the automatic inference of an Arabic lexical ontology based on different Arabic/English language resources.
