In order to understand planetary formation and evolution, we must consider observations, measurements, and predictions of Earth's deep interior in their appropriate temporal context. The paucity of information available for the earliest time period of Earth's history requires collaboration between researchers of different disciplines to discuss latest findings and brainstorm about future research directions. The 2017 Gordon Research Conference on the Interior of the Earth has the theme "from Earth formation to the present day", and will synthesize new research on planetary interiors across a broad range of disciplines including, but not limited to, seismology, geodynamics, mineral physics, geochemistry, geomagnetism, petrology, tectonics, and planetary science. This conference includes multidisciplinary sessions dealing with the structure, dynamics, chemistry, and evolution of the deep interior through time. Cutting-edge research findings will be presented on these topics from a broad suite of disciplines, defining the most pressing questions about planetary interiors and their evolution to the present day. The conference format provides the opportunity for junior scientists and graduate students to present posters and exchange ideas with leading researchers across disciplines in a collegial atmosphere. Regular discussion sessions and informal gatherings contribute to the tradition of fruitful and lively exchange between scientists at all levels in a cross-disciplinary format.
