Talks
I generally prefer giving blackboard talks, but sometimes slides are simply better suited. Here is a list of selected talks and slides (in pseudorandom order…).
- Online talk for the Majorana-Raychaudhuri Seminar Series presenting my paper on fingerprints of a non-inflationary universe from massive fields: slides
See also the presentation on YouTube below.
