Hello and welcome to my personal website! Here I am posting about my ongoing academic research. My main academic interest is in the use of geospatial data science and computational applications in geography, humanities, and archaeology.

I was first introduced to the significant role of geospatial applications in 2011, during my undergraduate at the Vrije Universiteit and Wageningen University in the Netherlands. Afterwards, I obtained my graduate degree at Koç Unversity in Istanbul, where I utilized my technical skills to support research aimed to document and analyse Turkey’s rich history and archaeological cultural heritage.

Over the years I have broadened and diversified my skills and interests by teaching GIS (Geographic Information Systems) in archaeology and history, organize summer schools, work in several research projects, as well as by participating in a ERASMUS+ capacity building project in Kufa, Iraq.

After obtaining my MA I worked as a full-time lead Geospatial Data Scientist and Research Fellow in an ERC-funded Horizon 2020 Research Project (UrbanOccupationsOETR) at Koç University. Here, I developed the geographic content management system of the project, and worked on research projects that incorporate Computer Vision/Machine Learning for feature extraction of Historical Maps, Network Analysis and the use of Geospatial Mobile Survey Applications for academic public outreach activities.

Currently, I am pursuing a Ph.D. in Geospatial Data Science at the University of Glasgow , focusing on the use of historical maps and census data to gain a better understanding of urbanization using geographical variables such as population changes and network accessibility.

Below depicts a fully functional 2.5D model as well as a digital elevation model of Barcın Höyük. This model was created for the Barcın Höyük excavation symposium in 2016. It is based on top and bottom elevations of excavated contexts, during 7 years of the project. The model was created by using ArcScene, CityEngine Webviewer and runs on OpenGL. Open the full viewer for better controls and guidelines.
