2020 Knuth Prize is awarded to Cynthia Dwork [pdf]
I took a class senior year with Cynthia which tried to cover some of the things that she had discovered. One of most surprising things about her work is that she brings this full algorithmic firepower to problems that I had always considered outside the realm of mathematics - fairness and privacy. Some of her greatest achievements, I think, are figuring out what problems to solve (and of course solving them). She really stood out as one of our best faculty even in a very crowded room.
