Emre Turkoz received his B.Sc. degree in mechanical engineering from Bogazici University, Istanbul, Turkey. He completed the M.Sc. degree with the same university under the supervision of Prof. Murat Celik.

His thesis work was on the modeling of the inductively coupled plasma focusing on RF ion thrusters. Emre has developed a model to simulate the plasma characteristics inside the discharge chamber of RF ion thrusters. The model has three components which are listed as the electromagnetic model, the fluid model and the transformer model. The electromagnetic model handles the evaluation of the electric and magnetic fields that affect as the Lorentz force on the plasma. The fluid model solves the fluid equations for the three species in the plasma: Ions, electrons and neutrals. The transformer model is used to represent the matching network. The model equations are solved in a 2D axially symmetric domain.

In a joint project with Firat Sik, Emre has been developing a PIC-DSMC algorithm for ion optics simulations. This study is based on the kinetic model for the plasma, where ions and neutrals are represented with macro particles and collisions are modeled according to the Direct Simulation Monte Carlo (DSMC) scheme

During the summer of 2013, Emre visited the Princeton Plasma Physics Laboratory (PPPL) and spent three months working on the modeling of RF plasma cathodes and arc discharges.

Emre began his Ph.D. studies at Princeton University in September 2014.
