BIOGRAPHY

 He was born in1958 in Denizli-TURKEY. He finished primary school in 1969, middle school in 1972, high school in 1976.  He got his undergraduate degree from the department of Mathematics in Atatürk University in 1980. He taught mathematics for five years in TOKAT in a high school. When he was teaching he appointed as research assistant to Department of Mathematics Education of Gazi Education Faculty in Gazi University in March 1985. Mean while he had registered to Mathematics M. Sc. Program of Science Institute of Gazi University and he got M. Sc. Degree in March 1987. He attained his Ph. D Course at the same Institute of Gazi University and he had taken the lectures in Ph. D Program successfully and soon after he had registered to Ph. D. Program of the Department of Mathematics in University of Wales in Aberyswthy. He got his Ph. D. degree in April 1992 at the same department of same university in the specific topic “ Banach Algebras and multiplier spaces of Banach Algebras” of Functional Analysis and Operator Theory and immediately he returned back to same department of Gazi University. He appointed to same department as a Assistant Professor in July 1993. He got his “Associate Professor” in October 1995 and soon after he appointed to same department as Assoc. Professor. He was in England for 70 days for Yök/ World Bank National Education Development Project at the School of Education of Leeds University. In July of 2002 he appointed to same department as a Professor. Still he is working at the same department Gazi Education Faculty in Gazi University and he has been head of the Department of Mathematics Education since 2004. He is married and he has three children.
