  • New recognitions and awards

    Over the last year, I have been named an External Profeesor of the Santa Fe Institute; of the Complexity Science Hub. I always enjoy supporting non-traditional research institutions, and look forward to continue my teaching and research in Santa Fe (which holds a special place in my heart) and I consider myself extremely lucky to count the great city of Vienna as my European home.

    I also had the great pleasure of being awarded the 2026 Young Scientist Award for Socio- and Econophysics from the German Physical Society (DPG) and the 2026 Erdős–Rényi Prize by the Network Science Society for my “foundational contributions to the theory of contagion on complex networks…” The physics of social systems and the study of how things spread are the great puzzles of my life. It is an immense honour to be recognized by peers for my contributions to these problems.

    P.S. This is you annual reminder that posts here are sporadic. News related to npj Complexity can be found on the journal homepage and all other updates can be found on the website of our Joint Lab.

  • npj Complexity

    Over the last three years, I have been working with the Nature Portfolio to launch npj Complexity; a Nature Partner Journal focused on all complexity and complex systems research.

    We had a soft launch back in 2023 and started publishing last year, in time for NetSci 2024 which we organized, sponsored, and hosted in Québec. The journal has been growing strong and we are now celebrating our first official anniversary with special collections on artificial life, information warfare, and group decision-making.

    P.S. News here are sporadic: Efforts related to npj Complexity can be found on the journal homepage, while updates related to my research group are on the websites of our Joint Lab, TGIR Center or Vermont Complex Systems Institute.

  • New Joint Lab Website

    Over the last few years, Jean-Gabriel Young and I have formed the Joint Lab. Most news and updates will be posted on the Joint Lab website going forward.

  • TGIR Center Renewal

    We received news last month that our Translational Global Infectious disease Research (TGIR) Center was renewed for another five years with a generous award from the NIH. I will continue serving as Director for our Mathematical & Computational Predictive Modeling Core.

  • APS Outstanding Referee Award

    I was awarded with a lifetime appointment to the American Physical Society’s Outstanding Referees program. This is an incredible honor. I am also proud to be the first awardee from the University of Vermont!
