The NCR DAYS is an annual conference held by one of the NCR partners. The conference is open for anyone, but is generally populated by (young) researchers employed in the Netherlands and direct neighbours. This small-scale conference is characterised by a high-quality content and excellent networking opportunities. The first NCR DAYS were held in Lunteren in 1997 and has been held each year since then with a brief interlude in 2009.
