Have you ever been to Picnic Day? It’s crowded but fun! You could plan to attend this coming April.

UC Davis is very strong in all sorts of biology, but I know that there are lots of other great places to study marine biology on the west coast, too. As a sophomore, it’s a bit early for you to start a “chance me / match me” post, but perhaps some people here will have suggestions of schools and programs that might give you inspiration or something to think about. I’m not well versed in marine biology personally, so I’ll leave that to others!
