Kay Ousterhoutshe/her/hers

keo@eecs.berkeley.edu

Hi! This is my second semester as a teaching professor at UC Berkeley, and I spent my first semester with many of you in 61A. I loved serving as a GSI for this class, CS61B, back when I was a graduate student at Berkeley, and I’m excited to be returning. Before becoming a professor, I built software designed to run on thousands of machines. I liked the software engineering challenges of balancing high performance with code that’s easy to understand and debug. In my free time, you can find me at Crossfit, on a hike, or wrangling my 3 children.
