Social Media Governance Initiative Affiliate Scholar | matthew.katsaros@yale.edu
Matt Katsaros is an affiliate scholar with the Social Media Governance Initiative at the Justice Collaboratory at Yale Law School.
Before this, he spent the past decade working in the tech industry (two years at Twitter and seven years at Facebook). During that time, he worked as a Researcher and Advisor supporting product teams on various online governance issues from developing machine learning, automation of detection of offensive content, and reshaping systems to better incorporate principles of procedural justice theory after users violate platform rules. Outside of his research interests, Matt is deeply engaged in his art practice working in textiles, natural dyes, and print making.
Projects
The SMGI's Spring '23 lab partnered with New_ Public to develop case studies looking at two specific design features of online platforms - reputation management systems and jury/tribunal systems. Over the course of the semester, students in our lab read through related research, collated examples of how these systems are used across different platforms, and interviewed practitioners who have developed these systems on major platforms resulting in these case study reports.
As the T&S field matures, policymakers, regulators, and industry practitioners are increasingly hungry for empirical evidence to guide their work. As part of the Social Media Governance Initiative, we downloaded an archive of 20 years of over 1,200 research articles written on various online Trust and Safety topics. Our postbaccalaureate fellow, Michael Bochkur Dratver, then began a systematic coding of all articles in the archive using a codebook that was developed collaboratively among those in our lab and feedback from others interested in the project.
The SMGI/JC hosted a two-day in person conference on Thursday and Friday March 30th and 31st, 2023 at Yale Law School. This two-day conference included presentations from a cross-disciplinary group of scholars and industry practitioners discussing their work exploring a range of issues of online governance.
