SOME HELPFUL FIRST STEPS FOR SOMEONE IN COLLEGE
The best first step you can take is to seek out a professor who is conducting research that seems interesting to you and volunteer to work in their lab. I recommend doing this around your sophomore year. That way, if you find that area of science isn't the right fit you can look for a different lab that is of more interest to you. There are so many exciting areas of science, so being able to explore different opportunities early will help you to find your perfect fit.
