Description
Cassie Kozyrkov is one of the most recognizable voices in data science and applied AI. As Google's first Chief Decision Scientist, she founded and championed the field of Decision Intelligence, an engineering discipline focused on how organizations turn data into better decisions. Over nearly a decade at Google she advised leadership on data-driven strategy and personally trained more than 20,000 Googlers in machine learning, statistics, and decision-making, helping teams put AI to work responsibly.

Her central focus is making data and AI safe, practical, and accessible. Rather than dwelling on abstract math, she reframes statistics and machine learning around the decisions they are meant to support, an approach that has resonated with technical and non-technical audiences alike. She is the creator of the widely followed "Making Friends with Machine Learning" educational series, which distills core ML concepts into plain language for a general audience.
Kozyrkov is a prolific writer and keynote speaker. Her talks span AI strategy and adoption, Decision Intelligence, data-driven leadership, the future of work, and responsible AI. She has become a beloved figure in the data community, with a large following across LinkedIn and other platforms, and has been repeatedly recognized as a top voice in data science and AI. Her educational content is prized for its clarity, humor, and knack for turning intimidating topics into something approachable.
Her background is unusually multidisciplinary, with training that spans mathematical statistics, economics, psychology, and cognitive neuroscience. That mix informs her emphasis on the human side of decision-making, from framing problems well to avoiding the cognitive traps that lead to poor choices even when the data is sound. After leaving Google she continued to advise senior leaders and organizations on decision process and AI strategy while building her own venture.
For anyone learning data science, leading an analytics or AI team, or trying to use data more wisely, Kozyrkov's writing, courses, and talks offer a grounded, decision-first perspective. She stands out not for a single product but for reshaping how a broad audience thinks about statistics, machine learning, and the decisions they are meant to serve.
