Message:

I was born in Isparta, which is located in the southern part of Turkey, and is known for its hand-made carpets and beautiful rose gardens. My interest in chemistry started during my high school years, and afterwards I joined to the Middle East Technical University as an undergraduate student in 1996. After graduation, I got both my M.Sc. and Ph.D. degrees from the same university under the supervision of Prof. Dr. Engin U. Akkaya. During my graduate studies, I mainly focused on the development of fluorescent chemosensors, molecular logic gates and energy transfer cassettes, as well as on the design of new fluorophores. During my Ph.D., I received a scholarship from the Scientific Research Council of Turkey (TUBITAK) to work in the Stoddart group at UCLA. Shortly after joining the group as a postdoc, we moved to Northwestern University. Nowadays, I am really excited about being here and working on chemistry of the mechanical bond. My main research interests are (i)molecular electronics, (ii) metal nanoparticle assemblies, (iii) Donor-Acceptor oligorotaxanes and polycatenanes, (iv) metal-organic frameworks. Outside the lab, I am trying to learn about this beautiful part of the U.S., watching NBA games, playing soccer, and enjoying my time in Chicago (except winter).
