The goal of this 2-day workshop is to advance the science case for the Microwave Kinetic Inductance Detectors for application in future experiments at the Cosmic Frontier. The event will bring together detector experts, theorists and experimentalists to discuss all the relevant aspects of the development of a robust program leading to a series of future experiments. These include spectrophotometric surveys for Dark Energy, low background experiments for direct detection of Dark Matter and Cosmic Microwave Background experiments for Cosmology.
