Cost Actions are an EU funding mechanism to get scientists together to work on bigger projects. I am here at the EBI to work on gene regulation for the GreekC project. Yesterday there were talks, and today it is workshops and discussions. We are looking at use cases, models and ontology development. Chris Mungall just gave a presentation on the current state of the relations ontology and Go Cam. The opportunity to collaborate is wonderful, and I look forward to setting up collaborative practicum activities for our masters student cohort. Thanks to Martin Kuiper for bringing me in to this group.
