Cathy O'Neil is a mathematician, data scientist and the author of Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy. She will discuss the unintended negative consequences of using big data, including how so-called "objective" black-box algorithms have the potential to reinforce human bias in everything from sentencing to hiring workers.

She writes regularly for Bloomberg View about algorithms, and in 2017 she founded the consulting firm ORCAA to audit algorithms for racial, gender and economic inequality.
