The importance of x-ray science across a broad range of areas in science and engineering continues to grow. The Gordon Research Conference on X-Ray Science has a long history of bringing together leading scientists at the forefront of x-ray-based science. Planned upgrades to storage rings and ever increasing capabilities of X-ray lasers drive the growth in the breadth and importance of x-ray science. There appears to be no end in sight for the unparalleled growth in performance of accelerator-based x-ray sources. New developments in experimental techniques continue to push into uncharted territories in physics, chemistry, biology, materials science, and a host of applied sciences. With the balance between basic and applied science constantly evolving, the conference will provide a unique forum to exchange ideas for the further evolution of X-ray Science. An international list of speakers will describe the latest scientific and technological achievements in X-Ray Science as well as provide a view into the future. The conference, with its strongly interdisciplinary character, provides a stimulating environment to present the latest research in poster format, engage in discussions in a friendly setting, and exchange ideas with leaders in the field. We especially encourage young scientists early in their careers steps to participate and profit from this unique forum for exchange with leading scientists in a relaxed atmosphere. Selected posters will be given the opportunity for a short talk. The 2015 GRC on X-ray Science will again be held in conjunction with the Gordon Research Seminar (GRS). The GRS (July 25-26, 2015), a two-day meeting preceding the GRC, is specifically designed for graduate students and early career researchers. The meeting offers an opportunity for young scientists to present their work to their peers. It is expected that GRS participants will participate in the subsequent GRC.
