Here are some links to Math talks given in the past:
Acylindrically hyperbolic structures on groups - Balasubramanya
Sahana Balasubramanya: Quasi-parabolic structures on groups
Here is a video made by the team at ICMAT, where Sahana talks
about her journey in math and dance.
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.
