Poonacha K. Medappa

Assistant Professor (tenured), Information Management
Department of Management, Tilburg School of Economics and Management

I study how software gets built in the open: how open source projects are governed and funded, how organizations take part in them, and how generative AI is changing the work of developers. I combine econometrics with machine learning to measure things that are hard to measure, like the novelty of a piece of code.

OpenCodeNet

A crowdsourced, open database of labelled code commits for training and benchmarking models that evaluate software code. More than 3,000 code snippets are labelled on novelty and usefulness, and researchers at Tilburg University, HEC Paris and SKEMA Business School use the data to study the antecedents of innovation in open source projects.

About

Before academia I spent several years in industry: designing embedded systems at Larsen & Toubro and working as a business analyst in Cognizant’s data warehousing and business intelligence practice. That experience of how software is actually built and used still shapes the questions I ask. I completed my PhD at HEC Paris under Prof. Shirish C. Srivastava and joined Tilburg University in 2019.
