from 17.16  IRTG "Fun Poster" Session and Happy Hour

We asked IRTG fun-poster contributors to venture away from conventional conference posters – to creatively combine a description of their doctoral project (conceptual idea, findings and/or state of progress) together with more personal aspects, like "ups and downs" experiences, favorite advice, favorite mistake, words of wisdom for future doctoral researchers ... Join us to see what they came up with!
