Publications, News, Teaching

I am an Assistant Professor at Design and Analysis of Communication Systems (DACS), The University of Twente, NL.  

My research aims at understanding, designing, and developing solutions for efficient networking, mostly in the context of spectrum sharing. You can see my UT profile page here. Also, here is a short introduction of myself. On March 2017, I am granted the title of Docent in Computer Science at the University of Helsinki, Finland. During 2017-2018, I was on N2Women Board as one of the mentoring co-chairs. I had my PhD degree from Bogazici University, Turkey in 2012.

For students:
- If you are student at UT, you can check the list of open assignments at DACS.
- Unfortunately, I do not have paid PhD/MS openings at the moment. You can check UT's portal for the vacancies.
