I look at their faculty pages, and graduate students. Like here.
Most of the graduate students have brief statements about where they have studied, and what their current research is on. (My doctoral research at Northwestern U. was in philosophy of language, linguistic semantics, hermeneutical theories, and metaphor theory, and how metaphor refers.)
What stands out to me is that a significant number of U-Michigan grad students in philosophy are working in the areas of ethics, moral philosophy, and metaethics.
Metaethics has special interest to me, since being introduced to metaethical studies by Nietzsche, as an undergrad in the 70s. Today I bought and began to read Metaethics: A Short Companion, by J. P. Moreland and David Horner.
"Some of the most interesting questions and debates in ethics are metaethical ones, such as Is morality something grounded in the nature of things, or is it a human construction? Are moral values objective, or are they relative to different individuals or cultures? Does morality depend on God, and if so, how?"
