Personal Details:

Vasques Filho holds a bachelor's degree in Engineering Physics from the Federal University of Sao Carlos (UFSCar), in Brazil. After graduating, he went to work in the industry, returning to academia after a long break in 2015. He obtained his PhD in Physics, in the area of complexity and network theory, at the University of Auckland, in New Zealand. His thesis explored the structure and evolution of large social networks. During his PhD, he was part of several different projects involving networks, such as collaboration networks for scientific and technological innovation, networks of political power and political activity, and correspondence networks in the modern Portuguese Empire. He is interested in developing new methods and expanding the application of complex systems concepts to the study of the humanities and social sciences.

Research Interests:

Networks of political and economic power
Structure dynamics of networks and evolution of communities
Collaboration networks for scientific and technological development
Influence and the spread of knowledge and ideas

Research projects:

"Linked Art" – Exploratory Project on the Use of Network Analysis in the Field of Art History

In the course of the seminar "Network Science in the Humanities", which Demival Vasques Filho conducted in the summer semester 2020 in the Mainz Master's programme "Digital Methodology in the Humanities and Cultural Studies", the students Sophia Renz and Vanessa Tissen started their project. 


Fälschungen X Netzwerke

Kunstfälschungen stellen nicht erst seit dem aufsehenerregenden Fall um Wolfgang Beltracchi eine Herausforderung für den Kunstbetrieb und seine sammelnden und bewahrenden Institutionen dar. Ab Ende des 19. Jahrhunderts erschien die Zeitschrift »Mittheilungen des Museen-Verbandes – als Manuscript für die Mitglieder gedruckt und ausgegeben«, die aktuelle Vorkommnisse und Erkenntnisse rund um aufgetauchte Fälschungen und Verdachtsfälle publizierte.

Negotiating social relations in collective and affiliation-based networks

Social relations are usually negotiated within a collective structure. In general, actors belong to social units or take part in social events where pairwise interactions (individual to individual) are over-simplistic. Nonetheless, current historical network analysis relies greatly on this type of interaction. Instead, we aim to investigate interactions between individual and collectivities, employing affiliation networks, and how these interactions affect the former.
