Dr. Pah Chin Hee serves as the Head of Department of Computational and Theoretical Sciences, Faculty of Science, International Islamic University Malaysia (IIUM) since July 2011 to December 2016 He graduated from Malaya University with Bachelor degree in physics and Master degree in Mathematics. Then he continued to pursue PhD under supervision of Prof. Dr. Nasir Ganikhodjaev at International Islamic University Malaysia. His research interest is statistical mechanics and number theory. He published a number of papers in Journal of Statistical Physics, Journal of Mathematical Physics, Theoretical of Mathematical Physics, Letter of Physics, and etcs. He also became reviewer of a few journals.
He was the Physics program coordinator and assisting in setting up the Physics Department's program. Throughout his service in IIUM, he was assigned the task to run the IIUM Mathematics Competition from 2007 to 2016. The event is now a national event approved by Ministry of Education. He was also active in mathematics education by conducting workshop and invited as guest speaker for school teachers.
