Sure, but please bear in mind that I'm just trying to repeat what she told me more than eight years ago.
As I recall, she was on track to graduate with a dual degree BS in Mathematics and Natural Science with a minor in Philosophy (not sure if I said that right), and was considering her options for graduate studies.
She said that she had spoken with various Professors (at University of Michigan in Ann Arbor), and came to me (we were together at the time, and she was expecting) and told me of her desire to pursue an independent study for her Masters degree, and that she wanted to study the Philosophies of Math and Science. I didn't really see a problem with it, other than to tell her I thought that it would basically leave her with only job prospects in academia, but she thought the same as well and accepted it. I think she actually had to write some proposal to be accepted at U of M with this course of study—but we eventually realized it was completely infeasible financially for us to pay for her Graduate Studies, so she found some government program that was giving a very substantial stipend to students studying Biostatistics and studied that instead.
Anyway, I know it's not much info , but I hope that helped.
