In 2015, after nine years as a research astrophysicist across global labs—including a pivotal stint at Stanford University exposed to Silicon Valley’s machine learning boom—I transitioned into industry data science. In this talk, I share the core lessons learned from this journey. I cover how to successfully navigate the leap from academia, how to stand out to industry recruiters, and what “data science” truly means in practice. Finally, drawing on my extensive experience in pro bono work, I explore how to effectively develop and deliver impactful data science projects for the third sector.
