IMPORTANT UPDATE: due to COVID-19, travel restrictions, and concerns over the health and safety of our mentors, hosts, and participants we have decided to hold CNWW 2020 virtually this year. CNWW aims to connect people across borders to solve interconnected problems. Virtual CNWW will be limited to 80 participants selected from the application pool and will be free for all participants. Existing applications for the physical meeting in Québec will be considered for the virtual meeting.

The event will be larger, with a more flexible structure. Note that the dates may change. We will share details soon and are leaving applications open
here. We apologize for the inconvenience and we appreciate your flexibility. CNWWs handle turbulence just fine.


The Complex Networks Winter Workshop (CNWW) is an international school that offers an extraordinary opportunity for participants to engage in rigorous transdisciplinary complexity science research alongside some of the top researchers in the field of networks. The CNWW is designed for graduate students, postdoctoral fellows, and professionals. The lectures will present open problems and recent advances in the field of complex networks. Participants of this program will collaborate in small transdisciplinary research groups involving other participants as well as faculty. All course lectures will be given in English.

Program Dates: TBA

The CNWW is a collaboration between the University of Vermont Complex Systems Center and the Sentinel North Program of the Université Laval.

    Antoine Allard
    CNWW Director

    Assistant professor, Département de physique, de génie physique et d'optique, Université Laval, Québec, Canada

    Antoine's research combines statistical mechanics, graph theory, nonlinear dynamics and geometry to develop mathematical models of complex networks and to study the structure/function relationship specific to complex systems. His recent projects involve the mapping of real complex networks unto hyperbolic space to characterize the evolution of international trade, the use of greedy routing to unveil the spatial organization of the brain at various scales and across species, and the analytical solution of percolation on networks with a strong induced core-periphery structure to assess the potential of the Zika virus as a sexually transmitted infection.

    Elizabeth Hobson
    Assistant Professor, Department of Biological Sciences, University of Cincinnati

    I am a biologist who specializes in animal behavior, behavioral ecology, cognitive ecology, and social cognition. My research focuses on social information: what animals know about their social worlds, how they come to know it, and what they do with that information.

    To address these questions, I integrate aspects of ecology and evolution to determine how the combination of sociality and cognition affect the emergence of group social structures from a combination of individual-level social actions, cognitive abilities, and decisions about future interactions. Combining this perspective into a feedback loop, and developing and applying new quantitative tools, allows me to back-infer what animals know about their social worlds by looking at how their decisions about social interactions are contingent on different kinds of social knowledge. Detecting the use of social knowledge provides new insight into the connections between social decisions and cognitive processing, how they can be affected by ecological dynamics, and how they can lead to the evolution of complex sociality.

    Much of my previous research focused on avian sociality, where I investigated social behavior and network structures in parrots. In my current research I apply these tools to a much wider range of species, from ants to primates, and even humans, while incorporating more quantitative and computational approaches.

    I am currently an Assistant Professor at the University of Cincinnati. My goal for research in my lab is to use rigorous comparative methods and an evolutionary perspective to discover ways in which the extreme sociality of some species emerged, through investigating what individuals understand about their social worlds and the strategies individuals use to balance the costs and benefits of social living.

    Daniel B. Larremore
    Asst. Professor, Univ. Colorado Boulder
    BioFrontiers Institute & Dept. of Computer Science

    My research focuses on developing methods of networks, dynamical systems, and statistical inference, to solve problems in social and biological systems. I try to keep a tight loop between data and theory, and learn a lot from confronting models and algorithms with real problems.

    I obtained my PhD in Applied Mathematics from the University of Colorado Boulder in 2012, advised by Juan G. Restrepo, after which I spent three years as a postdoctoral fellow at the Harvard T.H. Chan School of Public Health studying the genetic epidemiology of malaria in the Center for Communicable Disease Dynamics. I then joined the Santa Fe Institute as an Omidyar Fellow until 2017, when I joined the faculty at the University of Colorado Boulder in the Department of Computer Science and the BioFrontiers Institute.
    Malaria's antigenic variation and evolution - The var genes of the malaria parasite P. falciparum evolve according to complicated and unknown rules, with selective pressures at multiple scales both within hosts and between hosts. I create and use mathematical tools to understand the structural and evolutionary constraints on var gene evolution, and their relationships with parasite virulence, population structure, and epidemiology.

    Networks and theory - The processes that generate complex networks leave hints about themselves in the patterns of edges, and the relationships between those patterns and vertex metadata. I work on mathematical descriptions of graph ensembles, inference of community structures, vertex ordering or ranking, and using metadata to better understand network formation.
    The scientific ecosystem - The scientific method of hypothesis, experiment, and conclusion poorly describes modern scientific discovery and productivity. Instead, science is done by people who play various social roles in the ecosystem of science. I investigate faculty hiring, productivity patterns, scientific careers, and the dynamics of discovery through large-scale data collection and modeling.

    Assistant Professor of Ecology and Evolutionary Biology
    Brown University

    C. Brandon Ogbunu is an Assistant Professor in the Department of Ecology and Evolutionary Biology at Brown University. He is an evolutionary systems biologist, and uses experimental evolution, mathematical modeling, and computational biology to better understand the underlying causes and consequences of disease, across scales: from the biophysics of proteins involved in drug resistance to the social determinants underlying disease. In doing so, he aims to develop theory that enriches our understanding of the evolutionary and ecological underpinnings of disease, while contributing to practical solutions for clinical medicine and public health.

    CNWW was the perfect scholarly vacation. I learned so much, made new friends, experienced a beautiful city, and had a safe and supportive environment to take intellectual risks beyond what my typical responsibilities allow. I truly learned something from every single person I met at CNWW, and each welcomed me as someone from whom they could learn as well. I returned exhausted and exhilarated, brimming new knowledge and perspectives and excited for the cross-disciplinary connections I made with scholars from around the world. I would highly recommend participation in CNWW; the experience made me a better scholar and brought renewed vigor to my work. I am so thankful I had the opportunity to participate.
