I’ve always loved digging into the science and math behind my work. At Microsoft, I got deep into computer science. At the foundation, it’s computer science plus biology, chemistry, agronomy, and more. I’ll spend hours talking to a researcher or an expert, and then I’ll go home, dying to tell Melinda what I’ve learned I can’t imagine a better way to spend the bulk of my time. #TBT
