Personal profile

Research profile

George Fletcher is an Associate Professor at the Department of Mathematics and Computer Science, Information Systems WSK&I at Eindhoven University of Technology (TU/e) and chair of the Database Group. His main area of study is data intensive systems and he is particularly interested in query language design and engineering, foundations of databases, and data analytics as well as data integration and data science

He is currently investigating data engineering challenges in the management of massive graphs such as social networks, linked open data, and biological networks, as well as foundations and engineering of graph query languages, graph data analytics.

Academic background

George received his PhD in computer science from Indiana University Bloomington, where he was a member of the IU Database Group. Before that, he received a bachelors degrees in mathematics and cognitive science from the University of North Florida. He is also a visiting Research Fellow at Birkbeck, University of London. He also worked as a visiting professor at INSA Lyon, the Institut National des Sciences Appliquées de Lyon, and the University of Lille.
