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 (Zhi Hao Lim, [email protected]), and Programming Consultant (Yucheng Wang, [email protected]) can be contacted remotely. Yucheng Wang can help you with the programming and testing of new experiments in oTree (Python) and Qualtrics.

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