Ali Seyhun SaralBehavioral Data Scientist

About

Hi, I'm Ali.

I'm a Data and Behavioral Scientist working at the CEB Secretariat, UN Common System. An economist with a data science and software developer skill set, I build statistical models for analysis and prediction, develop data pipelines, software, and dashboards, create machine-learning and LLM-supported tools, and design causal inference strategies and experiments to understand human behavior and inform policy.

I have an academic background. I hold a PhD in Economics and Management from the University of Trento, Italy. After my doctorate, I worked as a researcher and lab manager at institutions including the Max Planck Institute for Research on Collective Goods (now Max Planck Institute for Behavioral Economics), the University of Bologna, and the Institute for Advanced Study in Toulouse. (See Experience section for details.)

Along the way, I have been fortunate to work with researchers across many disciplines: economists, psychologists, anthropologists, biologists, computer scientists, and mathematicians. Together with my co-authors, I have published a variety of work on cooperation, reciprocity, group decision-making, social learning, cultural evolution in impactful field-specific and interdisciplinary journals. (See Research section to read the papers.)

I am an experimentalist by training (and at heart), but my work draws on methods from several fields, including microeconomics, applied economics, causal inference, game theory, evolutionary biology, agent-based modeling, and social choice theory.
