The EGGS course took place during the first week of January 2015. We welcomed four international speakers and five from within Chile who contributed crucially to the success of this 5-day course. It was an intense but fruitful week, with classes taking place from 9 am to about 5 pm. We finished the week with a well deserved social event outdoors, involving informal interaction between the speakers and the attendants of the course. There was also good weather and nice food.
