Chelsea E. Manning is a technologist and network security expert, analyst, and consultant whose actions showed the world that the conscience of individuals can make urgent change through bravery and determination. Beyond her work as a security consultant, she is a transparency activist, an author, a DJ, and a public speaker. She lectures to draw attention to the social, technological, and economic ramifications of artificial intelligence, and on the practical applications of machine learning. She is a vocal advocate for government transparency and queer and transgender rights as @xychelsea on Twitter and through her op-ed columns for the Guardian and the New York Times. As of 2021, Manning works as a security consultant specializing in questions of privacy, security, and hardware optimization. Her wild journey is fully documented in Chelsea’s 2022 memoir, ReadMe.txt from Farrar, Strauss, and Giroux.
