Hashtag: #CNWW18

The Complex Networks Winter Workshop (CNWW) is a week-long 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.

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

The call for applications is open until 6 August 2018.

Up to 40 international graduate students, postdoctoral fellows and professionals from different disciplines will be accepted.

    Warwick Vincent
    Professor, Dépt de biologie & Centre d’études nordiques (CEN), Université Laval

    Dr. Warwick Vincent obtained his B.Sc. (hons) from the University of Auckland, New Zealand, in Botany and Cell Biology, and his Ph.D. in Ecology from the University of California at Davis, USA, with postdoctoral studies at the Freshwater Biological Association, United Kingdom. He was appointed to a faculty position at Université Laval in 1990.

    Dr. Vincent has conducted ecological research on lakes, rivers and coastal oceans in several parts of the world, including the subtropical convergence (South Pacific), Lake Titicaca (Peru-Bolivia), Lake Biwa (Japan) and the St Lawrence River. His research group has a special interest in the relationships between microscopic life at the base of aquatic food webs and physical aspects of aquatic ecosystems such as solar energy supply, temperature, mixing regimes and climate.

    Most of Dr Vincent's research, books and articles have focused on the polar regions, with his first expedition to Antarctica in 1979. Working with the USA National Science Foundation, he played an early role in the environmental protection of the McMurdo Dry Valleys of Antarctica (a Long Term Ecological Research Site), culminating in an internationally accepted management plan and Environmental Code of Conduct.

    Dr. Vincent is currently working with Spanish and Belgian collaborators on the Antarctic program RiSCC (Regional impacts and Sensitivity to Climate Change), but most of his research activities are in the Canadian North. He is a contributing author to the 'Arctic Climate Impact Assessment', is subprogram leader (microbial ecology) within the Canada Arctic Shelf Exchange Study, and leads Theme 2 within ArcticNet. He is working closely with Parks Canada in Quttinirpaaq National Park at the northern limit of Nunavut, on the diverse ecosystems of this region and their sensitivity and value as monitoring sites for global change.

  • Outline of Projects


    Before arrive visit our CNWW Slack to start forming project ideas.

    Forming Groups:

    -Groups can be any size. They typically break down to about 3-5 people
    -You can be in more than one group but be aware of managing your time and try not to spread yourself too thin
    -We prefer you to form multi-disciplinary groups and try to work with people in fields other than your own
    -This is a unique opportunity to try something new, so have fun!


    -There are specific times scheduled to work in your groups, but please feel free to use unscheduled free time to work as well
    -We recognize that a week isn’t necessarily enough time to complete all the projects you will begin at the CNWW, and we hope you will begin and continue collaboration with your fellow CNWW participants and CNWW faculty before and after the dates of the program.

    Faculty Mentors:

    -During the program, faculty will be available during the project work times to assist groups with their projects. Make sure to utilize their expertise and ask lots of questions. Feel free to involve them in projects too if you would like.

    Available Data Sets and Challenge Questions:

    -While you are free to use any data set or tackle any question you would like for the projects we will also list a few possible data sets and questions that you will have access to for the CNWW.


    -Group Presentation Day: December 20th
    -The presentations are a meant to be a quick overview of your group projects, they shouldn’t be more than a few slides.
    -Presentations are informal but must be between 10-15 minutes long per group - this includes time for questions. Please practice and time your talk beforehand.
    -We will post a sign-up sheet for the presentation schedule in the CNWW classroom

    Post Program Write Up:

    -A one-page write-up (one per group) about your project will be due by January 22, 2019.
    -We will release CNWW letters of completion upon receipt of write-ups.
    -We will post all CNWW write-ups on our website. If you are in the process of publication please still send Juniper your write-up and she will not post the write-up to the website, and will keep it in the private archive until notified of publication.
    -If you do publish a paper from a collaboration at the CNWW please let us know and send us a link so we can promote it and share your awesome work! This also helps us keep track of the success of the program.
