Apply to Olin. They want 50% girls 50% boys, so if a girl has a good profile she has better odds (because there are more male applicants). You never know! Keep in mind that first gen applicants are given a little leeway by the most selective colleges, provided they’re exceptional in every respect. So, your 32 would be excellent even at schools where that’s average, for instance.
Even if you’re not interested in women’s colleges, the colleges I listed (except for Smith but it is strong in engineering) aren’t isolated (Agnes Scott/GTech, Bryn Mawr/Haverford, Scripps/HarveyMudd).
Biomedical engineers are in demand after the Master’s level.
JHU - one of the best BME programs in the country- specifies that its master’s applicants can have any engineering degree with preferably 3.7 GPA (NOT easy) and research experience. So a BME degree is not necessary for a BME master’s. That would keep your options open.
You can also look into MD/PHD programs (post-degree) since they’re about medical research.
