The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.

INTRODUCTION TO ACCS

I am a professor of computer science in Boğaziçi University. My research interests are Theoretical Computer Science and Artificial Intelligence.

 

I am also a science writer, with a weekly column in Oksijen, articles in Herkese Bilim Teknoloji, and the author of the popular science books En Hakiki Mürşit, 50 Soruda Yapay Zekâ, and Yeni Dünya, Yeni Ağ.

In "civilian" life, I am known as an overall nice guy with a liking for science fiction, Western languages, and all kinds of funny things.
