Today, 31 October 2017, marks the last official day of CACHE-ITN. It’s hard to believe it’s four years since the project started. It’s been an amazing journey and we are getting some fantastic results and we hope we can continue our collaborations in the future. We still have quite a bit of work to do and more papers will be published. Please keep an eye on the CACHE website, as it’s staying open until 2020, to showcase publications and for the reports we have produced. Thanks to everyone involved with CACHE. Professor Mel Clark, CACHE-ITN PI.
