The National Institute of Statistical Sciences (NISS) is a consortium of high level researchers in Statistics who develop new methodologies and training solutions. I have attended several of their webinars and they are very good. They seem to offer one or two webinars per week and cover late breaking developments such as models for the COVID-19 pandemic.
