Sima joined the programs team at Impact Hub Istanbul in 2019. Her path crossed with Impact Hub while she was volunteering for a social enterprise focused on children's rights, which led her to initially support the Turkey Social Entrepreneurship Network project. For the past four years, Sima has contributed to the implementation of local programs and global initiatives such as the Social Impact Award, partnering with various organizations in the public and private sectors. In her free time, Sima creates collages using random objects, food, and materials she finds, and she enjoys photographing these collages without letting her cats disturb them.
