Marian-Gabriel Hancean

Welcome on my professional webpage!

I am tenured Full Professor at the Sociology Department of the University of Bucharest. At the same time, I am PhD supervisor at the Doctoral School in Sociology (University of Bucharest) and at the Interdisciplinary Doctoral School (University of Bucharest).
My current main research streams: (1) analysis of the antecedents and consequences of scientific collaboration; (2) statistical modeling of COVID-19 human-to-human transmission networks;(3) analysis of transnational social fields and transnational migration networks.
Since 2021, I coordinate the Center for Advanced Studies in Organizations and Complex Networks (a research center embedded in the Department of Sociology, the University of Bucharest).
Details on my publication record, research work and academic courses are to be found on this web page.
I keep an updated stream of news on my academic activities. Furthermore, my academic profile can be accessed on several electronic platforms such as: GoogleScholar, brainmap, ResearchGate, ORCID, ResearcherID and Academia.edu.
