The 9th International Conference on Computational Physics (ICCP9) will be held at the National University of Singapore, Singapore during 7 - 11 January, 2015. The conference is jointly organized by the Department of Physics, Department of Mathematics, the Institute of Mathematical Sciences at the National University of Singapore, and the Institute of Advanced Studies at the Nanyang Technological University and the Institute of Applied Mathematics and Computational Mathematics in Beijing, China. ICCP9 is the 9th conference in the series. The most recent ICCP conference was held in Hong Kong in 2013 (http://www.math.hkbu.edu.hk/ICCP8/). ICCP9 aims to provide a platform for computational physicists, mathematicians, materials scientists and engineers to share their recent developments in frontiers of theory and numerical methods as well as applications in computational physics and exchange ideas. The conference will consist of plenary lectures, mini-symposia with invited and contributed oral presentations, and poster sessions. Anyone who is interested in organizing a mini-symposium can submit a proposal to the conference chairs below for consideration. All researchers in computational physics, computational mathematics, computational science and applications or related disciplines are cordially invited to attend this conference.
