SIAM Workshop on Network Science (NS22) September 13-15, 2022
Virtual Workshop

The workshop will be held remotely and will include keynote presentations, contributed talks, and lightning talks. To facilitate participation from different time zones, each day the activities will start at 10:00am and end by 3:15pm EDT. Participation is open to the entire community (not only to SIAM members), but registration is required.

Network science is concerned with the structure and dynamics of graphs (and generalizations of graphs), dynamical processes on such graphs, and the design and analysis algorithms that compute with and on them. The goal of the SIAM Network Science workshop is to promote cross-fertilization and new research among the communities that study and apply networks, both inside and outside SIAM.

Outstanding Talk Awards

A team of experts selected three contributed and three lightning talks of the workshop for Outstanding Talk Awards. The evaluation criteria entailed content and delivery, with special attention to talks given by early-career researchers not associated with the organization of the event. The awardees of each category are included below and have received $250 USD each.

Lightning talk awardees:

  • Xue Gong for the talk “Generative Hypergraph Models and Spectral Embedding” (joint work with Desmond John Higham and Konstantinos Zygalakis).
  • Silvia Rognone for the talk "Characterisation of Large Spatial Motifs in Random Colouring Processes" (joint work with Vincenzo Nicosia).
  • Mateusz Wilinski for the talk "Network Reconstruction from Noisy and Incomplete Spreading Dynamics" (joint work with Andrey Y. Lokhov).
Contributed talk awardees:
  • Massimo Achterberg for the talk "Mean-Field Approximations of SIS Epidemics on Adaptive Networks" (joint work with Piet Van Mieghem).
  • Jonas L. Juul for the talk "Harder, Better, Faster, Stronger Cascades - or Simply Larger?" (joint work with Johan Ugander).
  • Leo Torres for the talk "Percolation in the Presence of Eigenvector Localization."
All times in the US Eastern Daylight Time.
