Black Lives Matter

The systematic and personal racism that caused the deaths of, most recently and publicly, George Floyd, Breonna Taylor, and Armaud Arbery ignited in me not only rage at the status quo but also shameful introspection asking the question "What have I done to help?" As an Asian male in academia, I have privilege and I cannot claim any personal experience akin to the discrimination faced by Black Americans everyday. But I can try to learn, try to speak up, and try to contribute. And you can too.

Here are some of the things I've found useful to help me be a better neighbor, better colleague, better friend, and better human being.
