Rana el Kaliouby is a rarity in both the tech world and her native Middle East: a Muslim leader and CEO, a woman in charge in a field that is still overwhelmingly white and male. Growing up in Egypt and Kuwait, el Kaliouby was raised by a conservative father who valued tradition--yet also had high expectations for his daughters--and a mother who was one of the first female computer programmers in the Middle East. Even before el Kaliouby broke ground as a scientist, she broke the rules of what it meant to be an obedient daughter and, later, an obedient wife to pursue her own daring dream. After earning her PhD at Cambridge, el Kaliouby, now the divorced mother of two, moved to America to pursue her mission to humanize technology before it dehumanizes us. The majority of our communication is conveyed through non-verbal cues: facial expressions, tone of voice, body language. But that communication is lost when we interact with others through our smartphones and devices. The result is a digital universe that's emotion blind. To combat our fundamental loss of emotional intelligence online, she co-founded Affectiva, the pioneer in the new field of Emotion AI, allowing our technology to understand humans the way we understand one another. Girl Decoded chronicles Rana el Kaliouby's journey from a nice Egyptian girl to a woman carving her own path as she revolutionizes technology. But decoding herself--learning to express and act on her own emotions--would prove to be the biggest challenge of all.
