Here are some links to Math talks given in the past:
Acylindrically hyperbolic structures on groups - Balasubramanya
Sahana Balasubramanya: Quasi-parabolic structures on groups
As part of the summer school, "Geometric Group Theory without boundaries", lectures on the mini course on "Acylindrical & Relative Hyerbolicity" were recorded and are available virtually. Here is the link to the playlist on youtube.
