Dr. Chris Harrison has been the best mentor I've had in college by far! He is such a great teacher, very accommodating, and incredibly tech-savvy so the COVID-19 interruption wasn't a terrible transition.
What I wish was different
Well of course I wish this experience had been in person rather than virtual being as I'm a bioanalytical researcher but most of us missed out anyway.
Advice
Just ask a professor to join their lab if you find their research interesting! You can see descriptions of their research online and almost everyone has their own personal website that is more in-depth (the good ones anyway).
