Accomplishments and Milestones

Visiting Scholar

November 2018 - Present

I currently hold visiting scholar positions at the Center for Integrated Quantum Materials (CIQM) at Harvard University (Prof. Bob Westervelt) and MIT Department of Physics (Prof. Riccardo Comin). My work here focuses on developing new types of optics for coherent control of X-ray wavefronts.

Group Leader

July 2015 - Present

I am working together with three excellent scientists (a postdoc and two Ph.D. students) in the Micro- and Nano-Optics Group. We strive for improving the focusing efficiency and resolving power of X-ray lenses. On the way, we develop new nanofabrication routes and optimize existing ones.


Summary & Research Interests

Everything Nano...

During my time as the leader of the Micro/Nano Optics Group in the Max Planck Institute for Intelligent Systems (MPI-IS), I followed a holistic approach to develop nanofabrication strategies for advanced optics for high-energy spectro-microscopy, as summarized in Fig. 1. This multi-faceted research approach led to the first point-focusing, approximation free soft X-ray kinoform lenses using gray-scale ion beam lithography (IBL) [1] (Fig. I). Recently, we used two-photon polymerization (2PP) based 3D nano-printing of high-efficiency X-ray lenses (Fig. II) with great preliminary results [2], and potential that is even more significant for the future. Furthermore, we used atomic layer deposition (ALD) and IBL to fabricate the first functional multilayer-Fresnel Zone Plates (Fig III) [3], and FZPs for coherent diffractive imaging (Fig. IV).

In the future, I am interested to use the nanotechnology expertise I have built over the years and transferrable fabrication and analysis skills to meet new challenges in nanofabrication and nano-imaging on a broader scope. I want to leverage my experience in nano-photonics, nano-fabrication to engineer sandbox devices, such as 2D and 3D ensembles of electronic and optically active nanoparticles and structures. My group will use cutting-edge microscopy tools to study these engineered systems under a variety of in situ and in operando conditions.



Ph.D. in Chemistry - 2011-2015

University of Stuttgart & Max Planck Institute for Intelligent Systems

I finished my dissertation in July 2015 with summa cum laude. I worked mainly on design, fabrication, and testing of X-ray optics. I concentrated my efforts mainly on developing focused ion beam lithography protocols, and characterization of the X-ray lenses.

M.Sc. in Nanotechnology - 2007 - 2010

Anadolu University - Turkey

I worked on hydrothermal synthesis of shape and size-controlled ZnO particles, fabrication of ZnO ceramics with a high degree of crystallographic texture and the characterization of their anisotropic properties. In addition, I continued my work on the vapor-solid transport method for synthesizing ZnO nanowires on the textured substrates.

B.Sc. in Materials Science & Engineering - 2003 - 2007

I finished my undergrad studies with the highest GPA among my classmates. In my B.Sc. thesis, I worked on the nanofabrication of ZnO nanowires by means of the vapor-solid transport method. This work was in relation to the thermoelectric properties of nanowires and their percolation behavior.

Scholarships / Internships


International Max Planck Research School - Advanced Materials

Ph.D. Scholarship

In 2011, I was selected from a multitude of candidates for the prestigious and competitive International Max Planck Research School on Advanced Materials with a scholarship that allowed me to move to Stuttgart for my Ph.D. studies.

National Institute for Materials Science

Japan - Visiting Researcher

During Fall 2008, I was a visiting researcher at NIMS in Tsukuba, Japan, in the fine particle processing group. I used the 12 Tesla superconducting magnet there to orient the ZnO particles I've synthesized for my master's work. This work led to a paper on anisotropic sintering shrinkage properties of textured ZnO ceramics, as well as another paper on the anti-bacterial properties of ZnO/HAP bio-composites.

Erasmus/Socrates Scholarship

Germany - Exchange Student

In 2006 Spring, I went to the Technical University of Darmstadt as an exchange student. This was an experience that significantly affected my future as I decided to continue my studies in Germany during this time.
