I am a lecturer at the Mathematics Department of Faculty of Mathematics and Natural Science, Syiah Kuala University, Banda Aceh, Indonesia.

I received my S,Si in mathematics (Informatics field) from Sepuluh Nopember Institute of Technology (ITS) Surabaya in 1997 and my M.Si in computer science from Bogor Agricultural Institute in 2006.

My teaching experiences since 1998 at some departments in Faculty of Mathematics and Natural Science and also in Faculty of Engineering. I have been taught some cources, such as Fundamental of Mathematics, Introduction to Information and Computer Technology, Programming Language in C, Computer Network System, Multimedia, Elementary Linear Algebra, Graph Theory, Human Computer Interaction, Computer Graphics, and Mathematical of Teaching and Learning Technology.

My research Interesting  in some scopes in computer science and mathematic fields, especially graphical visualization and computing of graph theory, speech recognition, and mathematical of teaching and learning technology. In mathematical of teaching and learning technology field, I was created or developed the graphical user interface (GUI) and interactive problem-solving media of mathematical teaching and learning for graph theory course, such as determining the graph connectivity, tree labeling, algorithms for finding Hamiltonian Cycle and Eulerian Circuit, and finding the cycle/cyle-base of simple graph.

Other Experiences:

1. As instructor/tutor of computer sciece olimpiade (OSN Informatics field) for high school level in Aceh Province since 2008 until now (2018).

2. As instructor/tutor of computer network training (CCNA1 to 4) at Cisco Academy since 2007 until 2010.

3. Multimedia reseach group leader at the Mathematics Department of Faculty of Mathematics and Natural Science, Syiah Kuala University since 2009 until now (2018).
