Despite implicit and explicit questions of my right to be in an elite space, I&#39m proud to report that when I graduated,我不知道自己是否能算精英阶层，但我很骄傲地宣称，I was the first black woman to earn a PhD in astrophysics in Yale&#39s then 312-year history.我，一名黑人女性，获得天体物理学博士学位，在耶鲁大学312年历史中是第一个。I am now part of a smal

I&#39ve lived the entirety of my life in the in-between,我一直生活在向交地带，in the liminal space between dreams and reality, race and gender, poverty and plenty, science and society.徜徉于梦想和现实，种族和性别，贫穷与富足，科学和人文之间。I am both black and a woman.

I was born in Korea -- the land of kimchi raised in Argentina,我在泡菜之国--韩国出生；在阿根廷长大，where I ate so much steak that I&#39m probably 80 percent cow by now可能因为吃太多牛排，我觉得现在我80%的成分是牛；and I was educated in the US, where I became addicted to peanut butter.然后我在美国接受教育，在这儿又对花生酱爱得无法自拔。During my childhood, I felt
