Yeah, maybe 'Quantitative Epistemology'. You'd probably be thrown right out of the Philosophy department though.

Noting that epistemology is concerned with the study of (the concept of) knowledge, and may (in principle) go beyond what’s involved in the purely scientific acquisition of such (if some non-scientific method for the acquisition of knowledge is to be accepted).

“Philosophy of science,” already mentioned, is probably a better fit. Once you go meta on science, after all, you are (arguably) not doing science anymore, so there is no harm in naming it a kind of philosophy.
