Eric Leung grew up in Oklahoma and learned a lot of math in high school. His friends wanted to go to medical school and he originally planned to join them. But instead he got interested in the emerging field of bioinformatics – math applied to medicine. After 6 years in graduate school, he made the big decision to leave without completing his Ph.D. But he was able to transition into the field of data science, and he now works as a data scientist at Disney. Eric and I met up at a public library here in Dallas, Texas to talk about his journey into data science, including his time spent learning through freeCodeCamp and ultimately contributing to our open source codebase. We also share our love of the US public library system, where we met to record this and where Eric worked when he was younger. And we talk about the ancient board game of Go.
