So F&M in my circles has a reputation for being strong in natural sciences, and empirically that seems to be supported by this PhD feeders study:
F&M made the Top 50 per capita, which includes both research universities and LACs, for Bio (#46), Chemistry (#33), and Physics (#26) (also Poli Sci at #29). Richmond only made the Chemistry list (#36), but I think this needs to be understood in the context of so many kids at Richmond being more interested in business and such than academia.
I don’t know about investment levels per se, and for sure Richmond is a much wealthier college than F&M in general. However, to me at least, things like those PhD numbers suggest F&M is at least investing enough in sciences to support high end student research opportunities.
