If you have a question about this talk, please contact Dr Sergio Bacallado.

In this talk I will start with a parametric network offline change point detection problem, showing consistent and optimal change point estimators and a phase transition phenomenon. I will then move on to a nonparametric dynamic network problem allowing for both across-time and within network dependence, accompanied with its application on a zebrafish neuronal activity data set. If time permits, I will also show our recent results on online network change point detection.
