I end up having the chance to speak on my current research a couple of times a year.

Occasionally I'll realize that the audience is some of the most well known names in my field and panic too much to do a good job. Having people ask to talk about my work afterwards always helps a lot with the subsequent spiraling thoughts. To be fair, I'd be happy even with criticism; that gives me something specific to improve rather than trying to figure it out on my own.

Been getting better at handling it as I gain more experience, but even then, being asked questions one-on-one really helps with knowing that the audience was genuinely paying attention.

Unfortunately I'm not the best at coming up with questions on the spot, I need time to digest the material. I admire people that can sit through a broad range of presentations and quickly have insightful questions for each one.
