She continued her research with projects in zooarchaeology and archaeobotany during her doctoral studies (2008-2015) and published her doctoral thesis as a monograph in BAR International Series in 2015 with the Titel “Archaeobotanical investigations of plant cultivation and husbandry practices at the Early Bronze Age settlement Küllüoba in West-Central Turkey: Considerations on environment, climate and economy”.

She gained work experience during and after her education in Turkey and Germany in different fields of social and life sciences; like working as restaurateur at historical buildings (1996-1998), as co-organiser of the “International Ceramics Symposium of Izmir, Turkey”, Dokuz Eylül University, Ceramic Department, Izmir, Turkey (1997-2002), as 3D-Modeller with the project “Troia VR”, 3D Reconstruction of antique Troy as “Virtual Reality” at Eberhard Karls University of Tübingen, (2001-2003), as lecturer for fine arts and Turkish language at the State-supported School for Adult Education (VHS Tübingen 2001-2017), as lecturer for environmental archaeology and archaeometry at the University of Tübingen (since 2015) and as researcher for the companies of the biotechnology in Germany (2016-2018).
