I’ve always thought of WUSTL as being more of a life sciences school. Wouldn’t it make sense to invest more heavily in that area?
We’re WAY off topic, but no @NerdyChica: They are already leading (and still continue to invest a lot) in those types of areas along with other schools such as VU, Emory, and of course Duke (as NRC would tell us), eventually a school can benefit from building up strengths in other areas that exist but can perform better and lag behind other disciplines. It is noticeable that very top schools have also excelled in (or have begun to excel) either the physical sciences, engineering, or both. It is certainly an area worth investing in as the bio-sciences in the research realm now rely on a much more interdisciplinary approach that requires the physical and computational sciences to move forward. Too bad only some very tippy top schools have been serious about making their undergraduate life sciences (outside of engineering) offerings reflect this 
. It will likely benefit graduate programs and research labs more if more life sciences students had more exposure to interdisciplinary problems, but oh well. Some schools just have a lot more money to throw around.
