This was one of my first thoughts too. They’re evidently okay with “heavily male” if they’re considering RHIT, which has fewer women (both in the absolute and as a percentage) than RPI has.
Also agree that Georgia Tech would be worth an app. It’s highly competitive for ChemE though (only MIT is considered stronger in this field). Still, an appropriate reach, and would be in budget if accepted (unlike UMich).
CWRU seems like a great fit to me. Their flexibility to explore/change majors would be a great asset. (They consider demonstrated interest very strongly, so take every opportunity to show that you’re serious about the school - open all emails and click on links, attend virtual events, etc.) There are so many program options, too - not only Chem and ChemE, but also Materials Science & Engineering, Polymer Science & Engineering, and an Engineering Physics major (which includes a concentration in any engineering field). Seems like the dance opportunities are good here too. Rochester also offers similar strength, variety, flexibility, and performing arts opportunities.
If she’d be interested in doubling down on languages and study abroad, there are a number of schools with International Engineering programs - a 5-year dual degree with the 4th year spent entirely abroad (one semester of classes and one semester of internship). UConn, URI, and U of Tulsa all have programs that offer both French and Spanish. (Tulsa’s program also includes non-engineering science majors, including chem.)
