Benjamin “Benji” Xie (pronounced ‘she’ + ‘eh’) is a postdoctoral fellow at the University of Washington Information School, mentored by Prof. Amy J. Ko. Benjamin designs and evaluates ways to use data to support equity and justice in educational contexts. He publishes his work to computing education and human-computer interaction communities. He received his PhD in information science from the University of Washington, where he was a National Science Foundation (NSF) Graduate Research Fellow and also a research intern with nonprofit Code.org. His doctoral research explored stakeholders’ interpretations of data for equitable computing education. He received his Master’s and undergraduate degrees in computer science from MIT, where he was an MIT EECS-Google Research and Innovation Scholar researching with Prof. Hal Abelson and MIT App Inventor.
