Walid Maalej was leading a research group on human and context aspects in software at the Technische Universität München (TUM). He studied computer science at TUM and at the National University of Singapore. He holds a Ph.D. degree on Intention-Based Integration of Software Engineering Tools. He also received a degree in Technology Management from the Center for Digital Technology and Management, an institution of the Bavarian Elite Network.

Walid published more than 30 peer-reviewed papers in renowned venues. He served as organizer, chair, and program committee member of national and international conferences in the fields Software Engineering, Requirements Engineering, Project Management and Knowledge Management.

Walid served as consultant and developer for several companies including mediawave, Siemens (Germany and Singapore), Deutsche Telecom, TCW management consulting, Rohde & Schwarz, and TCS. He is the initiator of the open source platform TeamWeaver and the scientific coordinator of the EU-Funded project FastFix.

Walid was distinguished by the Werner-von-Siemens-Ring foundation as the Junior Researcher in Computer Science for 2011-2013.
