On November 5, we were joined by Catherine D’Ignazio, co-author of the acclaimed Data Feminism (MIT Press, 2019). In her talk, D’Ignazio asked: Data science by whom? Data science for whom? Data science with whose interests in mind? She provided us with an introduction to data feminism, a way of thinking about data science and its communication that is informed by the past several decades of intersectional feminist activism and critical thought.
