The study of the commons has always benefited from complementary use of a variety of methodological techniques. Advances in the computer-based collection, processing, and analysis of data continue to bring rewards to methodological experimentation and innovation. Simultaneous advances in conceptually grounded institutional analysis approaches, such as the Institutional Grammar, support the integration of theory with these methodological techniques. Through this theme we welcome submissions that are applying various methodological techniques (e.g., qualitative, quantitative, and computational)  to advancing institutional science.  Computational methods include, for example, automated coding procedures, computer-supported qualitative research, digital commons, machine learning, artificial intelligence, and computer simulation. Also welcome are submissions that apply the Institutional Grammar in concert with these techniques. Program Committee sub-theme members: Seth Frey, Saba Siddiki
