Here are some answers from Instagram users:
"First year if you can. It shows commitment"
"Probably junior/senior year after you've done some labs and know about research"
This is a great question. Honestly, whenever you feel ready to get involved in research, go for it! If you feel like you have time to add this to your schedule without hurting your grades, the sooner the better. It will only give you more experience and the number of hours you can state on your application you've spent researching. However, grades are important that research in our opinion.
We hope this helps!
