I was born in Iran, in 1982. I have finished my BSc in Chemical engineering at Sahand University of Technology, Iran, with good marks in 2005. Then I completed my MSc degree and achieved the highest marks on my thesis: “Using Ultrasonic Energy for Preparation of Hydrodesulfurization Nano Catalysts” in 2007. I was also brilliant student in my university in both BSc and MSc degrees. I started my PhD program at the Reactor and Catalysis Research Center at Sahand University of Technology in 2008. I have been as a lecturer as well as researcher since 2008. I continued my PhD thesis under supervision of Ass. Prof. M. Haghighi and Prof. A. A. Babaluo, with the topic "CO2-Reforming of Methane on Innovative Nano-Catalysts Prepared via Non-Thermal Plasma Technology". Last year, I worked as a visiting researcher on the project of “Investigation of Fischer Tropsch Fe/Mn Model Catalysts” at Eindhoven University of Technology under supervision of Prof. Dr. J.W. (Hans) Niemantsverdriet. My focus is catalyst and reactor engineering, but I am not limited to these areas of research.
