Research

Constantinos Djouvas is a computational social scientist bridging computer science and social science to study social computing, text analysis, and political behavior. He builds end-to-end pipelines for the automatic collection, structuring, and analysis of political and social data, turning unstructured sources into research-grade datasets. He co-designs and evaluates cross-disciplinary research tools-notably Voting Advice Applications (VAAs) and DataPoll, a platform-agnostic system that enables large-scale analysis across social-science domains. Methodologically, he integrates machine learning, network analysis, and natural language processing to model complex informational structures, uncover latent textual and network patterns, and automate linguistic and argumentative analysis. Recently, he has focused on critically assessing large language models, characterizing and mitigating bias, and using information-distillation techniques to build smaller, interpretable models for rigorous bias analysis.

Research Interests: Computational Social Science; Social Computing; Text-As-Data; Political Behavior; Machine Learning; Natural Language Processing (NLP); LLM Audit & Bias; Model Interpretability.
