Ibrahim Yitmen received his PhD in Architecture from Istanbul Technical University, Turkey. Since February 2018 he has been an Associate Professor in Management of Construction Production at Jönköping University, Sweden. His research focus is mainly on Innovation in Construction involving socio-technical issues regarding digital transformation in AEC industry, and his recent special interest is on Digital Twin-based Smart Built Environment, Augmented Reality/Mixed Reality for Cognitive Buildings, Integration of Digital Twins and Deep Learning for Smart Planning and Construction, Blockchain Technology in Construction Supply Chains, Cyber Physical Systems for Construction 4.0, Integration of Unmanned Aerial Vehicles and BIM for Construction Safety Planning and Monitoring. Dr. Yitmen have published more than 100 research papers in refereed international journals and in peer reviewed conference proceedings. He has recently been the editor of the book titled "BIM-enabled Cognitive Computing for Smart Built Environment: Potential, Requirements, and Implementation" published by CRC Press. He was one of the guest editors of the MDPI Journal Applied Sciences for the Special Issue "Cognitive Buildings". Dr. Yitmen is currently leading research projects titled "Integration of Blockchain and Digital Twins for Smart Asset Lifeycle Management" financed by Smart Built Environment (Sweden), titled "Adapting Cognitive Digital Twins for the Production of Sustainable Modular Houses" financed by Vinnova (Sweden), and titled "Collaborative Digital Platform for Dynamic Workflows in Construction Production and Information Exchange Planning financed by Jönköpings Läns Byggmästareförening". Dr. Yitmen serves on the scientific committees of the international conferences held by the International Council for Research and Innovation in Building and Construction (CIB), American Society of Civil Engineers (ASCE), and European Council on Computing in Construction (EC3). He is an active Member of American Society for Engineering Management, USA since 2010.
