Feminist Philosophers provide a link to an essay on "how to mentor someone who doesn't look like you." I did find it slightly surprising that Professor Wong reported encountering so few philosophers of East Asian heritage, since my dissertation supervisor at Brown was of Korean descent, and before I jumped ship from Santa Barbara, I'd been working with a professor whose ancestry was Japanese. Admittedly, they were also each the only East Asians in their respective departments. Kind of an odd coincidence that I ended up connecting with both of them (even more oddly, they were both undergrads at Dartmouth together, though I don't think they knew one another at the time).
Anyway, check out Wong's tips.
