Ahmet Celal Cem Say (born 14 March 1966 in Ankara) is a Turkish theoretical computer scientist and professor of computer science. He is a full time professor at the Boğaziçi University Department of Computer Engineering in Istanbul, Turkey. Cem Say is the inventor of the QSI algorithm[1] for qualitative system identification, an AI task relevant in the study of qualitative reasoning. His work in complexity theory includes studies on small-space quantum autiomata and new characterizations of the complexity classes NL[2] and P[3] in terms of verifiers modeled by finite-state machines allowed to use only a fixed number of random bits.

Education

Cem Say was born in Ankara in 1966. He finished the high school TED Ankara College in 1983. He graduated from Boğaziçi University Computer Engineering in 1987. He received his PhD in the same department under the supervision of Selahattin Kuru in 1992.[4]

Academic career

He is a full time professor at the Department of Computer Engineering in Boğaziçi University since 1992.[5] He has been an active researcher, having published more than 80 scientific manuscripts with more than 700 citations.

Research areas

His research interests include theoretical computer science, quantum computing, artificial intelligence and natural language understanding.

Cem Say has an active profile in popular media. He has delivered several TEDx conferences in Turkey on artificial intelligence and robots.[6] He has appeared many times in national television channels in Turkey as a popular science commentator. He has authored two popular science books in Turkish: 50 Soruda Yapay Zekâ (Eng: Artificial Intelligence in 50 Questions) and Yeni Dünya Yeni Ağ (Eng: New World New Web). His popular articles on theoretical computer science have appeared in various local magazines.[citation needed] He has an active Twitter appearance, where he tweets in a daily basis on popular science and current political issues.
