Engin received his Ph.D. in Industrial Engineering from Middle East Technical University, Ankara, Turkey, in 2010. He also holds a B.Sc. and M.Sc. in Industrial Engineering from the same department. He worked (as a research assistant, instructor, then assist. prof.) in the Department of Industrial Engineering at Çankaya University between 2002-2011, (as an assist. prof.) in Turkish Military Academy between 2011-2012 and (as a postdoc, instructor) at Operations Planning and Accounting and Control group in Eindhoven University of Technology between 2012-2016. Engin is now working as a postdoc within IEBIS on ProSeLoNext project with Matthieu van der Heijden and Henk Zijm.


-Stochastic modelling of production/inventory systems, with a main focus on spare parts inventory systems

-Supply chain management,

-Maintenance optimization,
