General Application Guideline:


Positions are available for very competent applicants in M.Sc. and Ph.D. levels in Materials Sciences and Engineering, and Mechatronics Engineering, and Electronic Engineering programs depending on the availability of funds. If you think that your research interest fits into my ongoing research projects as well as research field in general, please submit full curriculum vitae, covering letter together with academic records (in MS Word or pdf formats) to me.


Please be informed that all programs in Faculty of Engineering and Natural Sciences (FENS) at Sabanci University accepts applications from competent students regardless of their science and engineering background  two times in a year for February and September entry. For September entry (Fall Term), the applications to FENS graduate programs will end on the 30th of May, 2012. Successful applicants are funded by two means: (i) full scholarship including both research stipend and tuition waiver, (ii) research fellowship funded by a project with tuition waiver.  Admission for externally funded (industry, foreign, etc.) very competent applicants are possible on the condition that the applicants meet the minimum requirements of the FENS, and the programs applied. Due to departmentless structure and multidisciplinary nature of our institute, there is no restriction on the previous engineering and science educational background of the applicants. Applicants should apply to a program from which they would like to obtain their degrees depending on either their previous education backgrounds or future carrier plan. I urge you to get familiar with the grad application procedure following the link;


and apply for PhD or MSc programs (whichever is relevant) in Materials Science and Engineering, Mechatronics Engineering and Electronics Engineering programs (depending on your undergraduate or Msc education or your career plan). Students are free to study under the supervision of professors from different programs. Admission to the program will be finalized if the applicant is successful in the interviews conducted by interview committee of the program for which application is submitted. Please do not hesitate to contact me either through e-mail or phone call for further information about grad study in our university and in my group. If you were to be successful in the interview, I would be able to support you through my announced projects. For international applicants, there will be a phone interview. Please let me know which program you have applied so that I can follow your application.


Qualifications and attributes expected from the applicants are:


- great character, organized, and motivated
- a degree from a nationally or an internationally well-known institution with a high GPA
- experimental, analytical, and computational skills
- strong interest in producing publishable results (
Publish or Perish!)


Open positions


Several research positions in Msc., PhD. and a Postdoctoral Research Fellow (PDF)  levels are immediately available.



1)          The Theoretical, Numerical and Experimental Investigation of the Mechanical Behavior of Multi-axial Laminated              Composite Materials. Positions Available: 1 PhD, and 1 MSc. positions are immediately available.  


In this project, we aim to develop a new multiaxial laminated composite through conducting combined numerical and experimental investigations on the mechanical behaviors of composite. In high-tech engineering structures (i.e. airliner, jetfighter, helicopter, high speed patrol boat, wind turbine blades), the most important parameter taken into consideration in design is to meet the strength, rigidity and stability requirements for structure in lowest possible construction weight. These requirements are best fulfilled by multi-layered structural elements such as composite materials. Developing new multilayered material configurations using conventional fibers (Glass, Organic, Carbon) in different woven fabric styles or multiaxial stackings yields very different mechanical characteristics and it is vital for a structural design engineer to understand the behavior of such hybrid laminates under statical and dynamical loading conditions. Developing such materials requires a multidisciplinary study including theoretical, numerical and experimental researches. The project aims to answer these needs. Experiences gained and results of this project will be used for developing new types of fabrics and laminate configurations having superior material properties and providing ultimate strength, rigidity and stability in construction elements. In the development of hybrid composite laminates, it is particularly important to investigate stress and strain fields at the interface of each lamina. To do so, the project will include the integration of Fiber Bragg Grating (FBG) optic sensors into the manufactured composites test samples. The candidates are expected to have a background or interest in composite materials, and instrumentations, design, and optic sensors. The suitable candidates should have previous degrees in Materials Science and Engineering, Mechanical/Mechatronics Engineering.


2-)        Monitoring Fatigue Behavior and Life of Fiber Reinforced Polymeric Composite Materials by Fiber Bragg Grating              Sensors. Positions Available: 1 PhD, and 1 MSc. positions are immediately available. 


This research focuses on monitoring the structural health of fiber reinforced polymeric composites under fatigue loading in situ by means of Fiber Bragg Grating Sensors embedded into composite structures. The immediate objective of the research is to develop a fatigue prediction model that uses strain as input data for calculating the remaining useful life and fatigue behavior of composites, and associated compact and on-board installable optic interrogation and signal and data processing systems. Within the scope of this project, a PhD and an MSc. positions are immediately available. The PhD candidates are expected to have a background or interest in instrumentations, design, and optic sensors. The suitable candidates should have previous degrees in Electronics Engineering, or Physics and are to be responsible for further developing our in-house optical interrogation system. MSc. candidates should have a background or interest in composite materials, and instrumentations, design, and optic sensors. The suitable candidates should have previous degrees in Materials Science and Engineering, Mechanical/Mechatronics Engineering. The MSc candidates will be in charge of conducting fatigue experiments on composite coupons with embedded FBG sensors.


3-)        The Development of a Smoothed Particle Hydrodynamics Model for the Deformation and Motion of a Bubble in a              Newtonian and Non-Newtonian Viscous Liquid under the Combined Effects of Gravity and Externally Applied Electric              Field.    


In this project, we will numerically investigate the effect of an electric field on the buoyancy-driven motion of a two-dimensional bubble rising through a quiescent Newtonian and non-Newtonian (Olroyd B fluid) liquid. The dynamics of the bubble will be simulated computationally using a Lagrangian meshless Smoothed Particle Hydrodynamics Method. Two different electric field models, namely, a leaky dielectric model, and perfect dielectric model will be used in order to account for the effects of the electric field, electric charge, and electrical properties of liquids. The numerical algorithm to solve this free-boundary problem will use SPH method to discretize Navier–Stokes equations and associated interface and boundary conditions. The droplet interface is modeled to be a finite-thickness transition zone across which the material properties vary smoothly, and surface tension and electric field effects are to be integrated into momentum balance equation by using a continuous surface force approach. This work also enables us to develop robust multiphase SPH algorithms to study other complex electrohydrodynamics problems widely encountered in engineering fields such as multiphase flow in drug delivery, and biomechanics. The suitable MSc and PhD candidates for this project are expected to have a strong background in mathematics, physics and fluid mechanics and also to have a capability of coding in Fortran or C languages. MSc, or PhD candidates graduated with degrees in Mechanical/Mechatronics Engineering, Chemical Engineering, Materials Science and Engineering, Physics, or Mathematics are highly encouraged to apply.
