Menglin (Miley) Liu

I am an Assistant Professor of Computational Social Science at The Chinese University of Hong Kong, Shenzhen, and an Assistant Professor (by courtesy) at the School of Artificial Intelligence. I also serve as the Coordinator/Advisor for the MPhil-PhD program at the School of AI. My research bridges political science and natural language processing (NLP), with a focus on American politics, urban governance, and the measurement of political behavior and public opinion.

I develop scalable NLP pipelines to extract meaning from unstructured political text and audio data. My projects include PoliPrompt, an open-source Python package for prompt optimization and LLM-based classification, and large-scale studies on latent ideology in congressional speeches, emotion and effort in open-ended survey responses, and political language in housing policy debates. I am also a cofounder of SurveyFluency, an AI startup for intelligent survey analytics. My research also explores the intersection of reinforcement learning and social science.

My work has been published in journals such as Local Government Studies and Cities, and presented in venues across computational social science. I have professional experience as a data analyst and regularly collaborate with political scientists and policy organizations to translate complex data into actionable insights.
