Keng-Chi Chang joins QSS

Keng-Chi Chang, who received his PhD from University of California, San Diego in 2024, is the newest faculty member in the Program in Quantitative Social Science. He joined the program in July 2025 and will be teaching QSS 20 (Modern Statistical Computing) in the 2025 fall term. 

Professor Chang works on dissecting the mechanisms of content moderation on digital media and unpacking the inner workings of AI systems such as vision and language models. His recently published article includes "COVID-19 Increased Censorship Circumvention and Access to Sensitive Topics in China" in the Proceedings of the National Academy of Sciences, "The Importance of Prompt Tuning for Automated Neuron Explanations" in NeurIPS Workshop, and "Connective Effervescence and Streaming Chat During Political Debates" in Journal of Quantitative Description.  He will be presenting "Propaganda or Parity? TikTok's Algorithm and Pro-China Messaging" in the upcoming 2025 American Political Science Association Annual Meeting.

Professor Chang's office is in Silsby Hall, which is the home of QSS and several other social science departments at Dartmouth.  QSS now has three full-time faculty members and is searching for a fourth.  The entire QSS community welcomes Professor Chang!
