Vincent Traag, PhD

Vincent Traag is a senior researcher at the Centre for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. His main interests are mathematical models in the social sciences with a focus on (social) networks. Traag is a core member of the Engagement & Inclusion focal area, where he studies the role of science in societal debates. In addition to his scientific research, Traag also acts as a bibliometric consultant at CWTS.

Traag obtained his Master in sociology (cum laude) from the University of Amsterdam (2008). Coming from a computer science background, and taking up mathematics during his studies in sociology, he went on to obtain a PhD in applied mathematics in Louvain-la-Neuve, Belgium (2013). He joined CWTS in 2015.
