Advice
It's always great to get involved in research early, but make sure you are genuinely passionate about the topic you choose so that when you're working full-time over the summer, you enjoy being in the lab and working. I'd also encourage you to build a strong relationship between your PI, direct supervisor if you have on (ex. postdoc/grad student) and yourself. It makes coming to lab a lot more fun when you know the people who are helping you on your path forward in research.
