The mastercommittee (MaCo) is an unique collaboration between the CDL and S.V.LIFE. It is not simply a collaboration between master students from the masters Chemistry and Life Science & Technology but also an internationally oriented committee: it was the first committee of the CDL and S.V.LIFE in which international students toke part! This made the committee a mixed group of people, which only turned out to be very positive! The committee strives to organize activities that brings all the master students together and strengthen their (chemical) bond. We can hereby think of two different types of activities: social activities and master lectures.
