If you want to learn a little bit about my research on fractons and have only 4 minutes to spare take a look at my Gong Show talk at Strings 2022 (you have to jump to 54:50).
As part of the North British Mathematical Physics Seminar series I have given an "Introduction to nonlorentzian geometry based on homogeneous spaces". They were geared towards graduate students and have been recorded on YouTube:
I have written an outreach article for the Solvay annual report 2018 where I describe part of my research of the last years in a hopefully accessible manner. You can download it here.
