Message of the Coordinator

The study day of last month in Liege was great success ! I'd like to thank the three plenary speakers for the fascinating talks. We started with Yurii Nesterov who showed us an innovative way to look at gradient free minimization by introducing randomness in the iterative process. In the afternoon, Heinz Koeppl from ETH Zurich, informed us about the design of algorithms for the estimation of chemical rate constants from time-series measurements of protein abundances in a cellular signaling system. We ended the day with a great survey on robust stability and control of hybrid dynamical systems delivered by Ricardo Sanfelice from the University of Arizona. I'd like to thank the plenary speakers for their inspiring talks but also the poster presenters for the quality of their work and their posters. Congratulations to the local organizers for putting together such a nice program and for making this such a pleasant meeting!
