Women In STEM is a non-profit branding design to encourage women to pay more attention to STEM fields. After I heard the story of Ada Lovelace who is the daughter of British poet Lord Byron, a mathematician, a computer program founder, and established the concept of the cycle and subroutines, I realized that women in STEM fields could make great achievements as well as men. However, over the past few decades, the number of female staff dropped rapidly in STEM fields. So I tried to build an organization. My goal is to raise awareness regarding this growing problem and encourage more women to work in Science, Technology, Engineering and Mathematics fields. What's more, Women In STEM is developed from a public intervention exercise: Interacting with people on the street using a question card, and giving them another card as a gift in return afterwards, creating a conversation and providing a means for interaction. The project evolved into a social impact design campaign through exchanging cards. By holding an art exhibition around this theme, the campaign seeks to engage and provide relevancy for women, whatever their jobs are, and make them interested in science, technology, engineering, and mathematics fields.
