(Career question) I’m going to graduate undergrad in one year + one semester. There are already grad programs I’m interested in… How soon should I start reaching out to potential grad school advisors?

There are a few research groups I’m very interested in and I think I have a good background to give me a strong chance of being accepted into their program.

I’d like some advice…

Is one year and a half too soon to start the process of reaching out and contacting them?

Or should I go ahead and start now?

I really have no idea which may be the better approach.

Also, in general, just an email to start out should be the way to go about this, correct? Anything I should do if no response is received?

Thanks everyone!
