I earned my BSc degree in Aerospace Engineering from Middle East Technical University in 2003. Subsequently, I attended the COMMAS (Computational Mechanics of Materials and Structures) course at the University of Stuttgart, where I obtained my MSc degree in Computational Mechanics in 2005 under the supervision of Prof. Dr.-Ing. Christian Miehe. Following this, I served as a PhD researcher at Eindhoven University of Technology in the Netherlands, where I completed my PhD in Mechanical Engineering in 2011 under the guidance of Prof. Dr. Marc Geers. Following a postdoctoral grant at the European Commission’s Joint Research Centre from 2010-2013, I worked as a postdoctoral researcher at the University of Oxford and as a Lecturer at St. Anne’s College, Oxford University, from 2013-2015. Since 2015, I have held the position of Lecturer, initially starting as an Assistant Professor, later promoted to Associate Professor, and then to Full Professor at the Department of Aerospace Engineering, Middle East Technical University. Throughout my career, I have had the opportunity to visit esteemed institutions such as Monash University in Australia (2017), Doshisha University in Japan (2018), Technische Universität Bergakademie Freiberg in Germany (2019), and Nanyang Technological University in Singapore (2020). I am actively engaged in professional organizations, being a member of EERA (European Energy Research Alliance), JPNM (Joint Program of Nuclear Materials), and ESIS (European Structural Integrity Society). Furthermore, I proudly serve as the national representative of Türkiye in ESIS.
