Iris D. Tommelein Technical Committee

Iris D. Tommelein is a Professor of Engineering and Project Management in the Civil and Environmental Engineering Department and directs the Project Production Systems Laboratory (P2SL) at the University of California, Berkeley.

She has been studying, developing, and applying principles and methods of project-based production management for the architecture-engineering-construction (AEC) industry, what is termed Lean Construction. Her pioneering research in Lean Construction includes teaming up with design specialists, general- and specialty contractors, owners, suppliers, and other stakeholders in order to increase process and product development performance. She is an expert on site layout and logistics, operations and methods design, materials management, and supply-chain management. She is involved in developing digital twins and related decision-support systems, enabled through the use of information technology systems that leverage sensor data, heuristic- and mathematical optimization as well as artificial intelligence (AI), and graphical and interactive user interfaces. Her current research focuses on takt planning.

Iris has led many industry workshops, hosted conferences on Lean Construction, and is actively engaged in consulting work. She has published over 250 refereed articles and book chapters and given numerous keynote lectures on her research.

Iris graduated as Civil Engineer-Architect from the Vrije Universiteit Brussel (VUB) in Belgium. She also holds a MS in Construction Engineering and Management, an MS in Computer Science (Artificial Intelligence), and a PhD in Civil and Environmental Engineering from Stanford. She was recognized with the Lean Pioneer Award 2015 from the Lean Construction Institute (LCI) and is a member of the National Academy of Construction (NAC).
