Summary Description:

We are seeking highly motivated Turkish or international PhD students to join our large research project funded by TÜBİTAK 2232 programme for outstanding researchers - focusing on structure, functioning and modelling of saline lakes ecosystems. The researchers will be principally working with Professor Erik Jeppesen (, Professor Meryem Beklioğlu (,, Assist. Professor Korhan Özkan ( and Professor Zuhal Akyürek ( as well as collaborating with researchers across a wide international network.


The project will be conducted at the Middle East Technical University (METU) Ankara and Mersin Campuses and the PhD Students may enroll graduate programmes of the Institute of Natural and Applied Sciences of METU Ankara Campus at the Biological Sciences and Civil Engineering Departments, Geodetic and Geographic information technologies programme, and the Institute of Marine Sciences at METU Mersin Campus.


PhD Position 1: 1 PhD position is on ecological modelling and remote sensing of saline lakes. The tasks involved in this PhD research project are:

• Monitoring and analysing saline lakes in Turkey and Kazakhstan by using remote sensing and GIS.

• Adaptation of lake ecosystem models (for example PClake-FABM) to saline lakes using existing data as well as data obtained during the project fieldwork.

• Using adapted catchment-lake ecosystem models to better understand potential regime shifts in saline lakes and their drivers.


PhD Position 2: 4 PhD positions are on experimental and field ecology of saline lakes. The tasks involved in these PhD research projects are:

• Conducting ecosystem scale replicated mesocosms experiments using new state of the art mesocosm experimental facilities at METU Ankara and Mersin Campuses that will be built in the first year of the project.

• Studying food-web ecology using stable isotopes and paleo-ecological approaches.

• Conduct fieldwork on numerous Turkish and Kazakhstan saline/brackish lakes.

• Conduct laboratory and microscopic analyses.

• Conduct cross-system analyses on the structure, biodiversity, ecosystem functioning of saline lakes using classical and trait-based approaches on the lakes sampled during the project as well as existing data from the literature

• Conduct cross system analyses to develop better understanding of regime shifts in saline lakes on the globe
