Selected publications


Dr Yasseri graduated from the Department of Physics at the Sharif University of Technology, Tehran, Iran, in 2005, where he also obtained his MSc in 2006, working on localization in scale free complex networks. In 2007, he moved to the Institute of Theoretical Physics at the University of Göttingen, Germany, where he completed his PhD in Complex Systems Physics in 2010. Prior to coming to Oxford, he spent two years as a Postdoctoral Researcher at the Budapest University of Technology and Economics, working on the socio-physical aspects of the community of Wikipedia editors, focusing on conflict and editorial wars, along with Big Data analysis to understand human dynamics, language complexity, and popularity spread. Dr Yasseri’s main research interest is in human dynamics, social networks, and collective behaviour.

Latest blog posts

Current projects

  • Elections and the Internet

    Participants: Professor Helen Margetts, Dr Scott A. Hale, Dr Taha Yasseri, Dr Jonathan Bright

    This site collects elections research at the OII. We are interested in exploring the extent to which data from the social web can be used to predict interesting social and political phenomena, especially elections.

  • The “Offensive Internet”? Examining Cultures of Hate and Prejudice Online

    Participants: Dr Taha Yasseri, Dr Kathryn Eccles, Dr Vicki Nash

    This project examines the cultures of offensive speech online. It aims to learn about how offensive material is created, about the actors who produce and disseminate it, and the ways in which it is challenged.

  • Online Social Networks

    An introduction to the analysis of online social networks, providing students with the tools necessary to undertake research on online networks, and to give an overview of the type of questions that these data can answer.

  • Big Data Analytics

    This course focuses on the statistical analysis, manipulating, and making sense of (already prepared) data.

  • Digital Social Research: Methods Core

    This course provides students with the opportunity to engage with the methodological, ethical and philosophical underpinnings of quantitative and qualitative social science research practices.

  • Simulating Society

    This course is about agent-based modelling, a fascinating technique for answering social science questions, based on computer simulation of real-world societies and real-world human events.
