I have been serving as a lecturer in Faculty of economics and business by the end of 2003, especially in public economics department. My interest is evolved around public economics hence my study and research are also developed around the subject. I have always tried to improve my ability through formal and informal education because my intention was to share my knowledge as much as I could. I believed sharing and transferring knowledge to others was not only to part of my duty but also part of spiritual enlightenment.
