The Columbia Experimental Laboratory for Social Sciences (CELSS) is an interdisciplinary resource for Columbia researchers in Economics, Political Science, Sociology, SIPA, and the Business School, as well as the Barnard Economics department. Its goal is to facilitate experimental research in the social sciences, with a focus on computer-based experiments, whether physically located in CELSS’ lab, or online.

CELSS' Lab Manager (Shuhua Si, [email protected]), and Programming Consultants (Victoria Geh, v[email protected] and Aryan Ranjan, [email protected]) can be contacted remotely. Victoria Geh can help you with the programming and testing of new experiments in oTree/Python, and Aryan Ranjan can help you with experiments involving Qualtrics or MTurk.

Our YouTube page has a growing number of tutorials to help you code and build your experiments. Current topics include mTurk and Qualtrics.
