Agree there are a lot of research opportunities in LACs. Not @MamaBear16 but I did research on strong STEM LACs this past year for my D. On East Coast and in Midwest some of the ones that came up a lot are, in no particular order:
Carleton
Swarthmore
Grinnell
Davidson (brand new science building)
Williams
Smith (women’s college)
I’m sure there are others, but thought I’d share.
Good luck in your search!
