The SIAM Activity Group on Dynamical Systems (SIAG/DS) presents the Red Sock Award for the best poster presentations in dynamical systems by a student or postdoc at the SIAM Conference on Applications of Dynamical Systems. Out of 95 posters presented during two evening sessions at DS19, which took place last week in Snowbird, Utah, seven received recognition at the end of the conference.

The prize is named in honor of James A. Yorke and his distinctive footwear, and each winner receives $100 and a pair of red socks. Red sock poster prizes have been awarded for over two decades, and the award was made an official SIAM Prize in 2013.


Five of the seven poster prize winners pose with their coveted red socks at the 2019 SIAM Conference of Applications of Dynamical Systems. Front row (left to right): Andrus Giraldo (University of Auckland), Stefan Awender (University of Alaska Fairbanks), Brittany Lemmon (University of Nevada, Reno), Rebecca Santorella (Brown University) and Priya Subramanian (University of Leeds). Back row (left to right): chief judge Alan Champneys, chief judge Alberto Carrassi, and James A. Yorke (for whom the prize is named).


The panel of judges was chaired by Alan Champneys and Alberto Carrassi. The awardees and the title of their prize-winning posters are as follows:

  • Jassem Bourahmah (Georgia State University): "Synaptic Dynamics and Bursting in Neural Networks"
  • Andrus Giraldo (University of Auckland): "Dynamic Complexity of Two Coupled Photonic Crystal Nanocavities"
