Hannah Lane describes herself as a human-centered designer and social entrepreneur. Basically that means she designs systems that help make the world a better place. While she began in the health space (specifically focusing on HIV/AIDS in Africa), she is currently working for a for-profit technology company that believes in using the tools it develops to work for social and economic justice all over the world. Most recently, she’s been down in Ferguson, MO helping to connect and organize the ongoing movement around the Aug. 9 shooting of Michael Brown. In the last few years, tools like Twitter and Facebook have been used by social movements from the Arab Spring to the Bring Our Girls Back campaign. They have succeeded in channeling and coordinating people's angry enough to do something; the question is what is that something? With a background in psychology and her current work in technology, Hannah Lane has thought deeply about these questions. How far can technology go in changing the world and to what extent are human problems still fundamentally human?
