The best place would be to start from the ML Collective: https://mlcollective.org/

They do some fantastic research in applied and theoretical ML. Rosanne Liu is a personal hero/role model of mine, and we all have a lot from the way she has organized this group and her career in general.

I really wish I'd known about this group back when I was an undergrad and just getting into DL research.

Let me know what your interests are, I can point you in the direction of some interesting people who might consider mentoring young undergrads.

All the best!
