The Debye PhD Committee (Debye AiO Commissie, DAC) exists in order to represent the interest of  all the different researchers currently working within the Debye Institute. Each research group is  represented by at least one PhD candidate. Together, the DAC unites the various research groups by organising activities like the Debye Sports Day at the beginning of each academic year and the social events during the Debye Spring School. The DAC also contributes to the educational programme by organising the biannual career-oriented Debye DO! Days event, where PhD candidates have the chance to discuss future career moves with employees across a broad scope of science-orientated jobs.
