AI is transforming how open source software is built, who contributes to it, and how scholarly work gets done—but the open source community is still working out what that means in practice. This panel brings together researchers, educators, and industry practitioners to examine AI's impact on open source from multiple angles: the empirical evidence on how AI-assisted contributions are being evaluated by maintainers, the practical challenges facing UC researchers trying to use AI tools in reproducible, open scholarship, the infrastructure questions that determine whether open source AI is even a viable option, and what decades of community building can tell us about where we go from here.

Sahiba Chopra is a PhD candidate in the Management of Organizations group at UC Berkeley Haas School of Business and a Data Science Fellow at the D-Lab. Her research interests lie at the crossroads of technology, innovation, and the labor market, and she is currently exploring questions about how generative AI might transform workplace collaboration. She has a diverse professional background as a data scientist across industries including fintech, cleantech, and media, and holds a BA in Economics and Chinese from the University of Maryland and an MS in Applied Economics from the University of San Francisco.

Sahiba Chopra is a fifth-year PhD candidate in the Management of Organizations group at UC Berkeley's Haas School of Business, advised by Professors Mathijs de Vaan and Abhishek Nagaraj. Her research examines how AI tools are reshaping collaborative work—specifically how they disrupt the social evaluation processes through which people assess and coordinate with one another in organizations. Her dissertation introduces "effort opacity theory," which explains why AI-generated contributions face systematic evaluation penalties even when their quality is comparable to human work. She combines large-scale computational methods, causal identification strategies, and controlled experiments in her research, and is herself an active participant in the open source ecosystem through GitHub hackathons and her own public repositories.

Marit MacArthur is a continuing lecturer in the University Writing Program at UC Davis, where she has taught composition, professional writing, and American literature for 20 years. Her work on AI and writing is grounded in a decade of interdisciplinary research on open source speech recognition tools, funded by the NEH, ACLS, and SSHRC Canada—giving her an unusually deep understanding of both the open source and the pedagogical dimensions of AI. She is a Principal Investigator on PAIRR, a $1.5 million California Education Learning Lab project spanning UC Davis, three CSUs, and four community colleges, and a co-investigator with the NEH-funded Center for AI and Experimental Futures at UC Davis. Her research has appeared in AI & Society, Computers and Composition, and Inside Higher Ed, and she serves as series editor for the journal Critical AI on GenAI and writing in higher education.

Tara Hernandez is Vice President of R&D Productivity at MongoDB and a UC Santa Cruz Computer Science alumna (1993). She is one of the original pioneers of continuous integration, having built CI tooling and managed the Netscape Navigator development team before helping prepare the original Mozilla codebase for public release—a foundational moment in open source history. She subsequently held engineering leadership roles at Pixar, Linden Lab, and Google (where she oversaw Kubernetes developer tools and Google Cloud Platform learning content) before joining MongoDB in 2022. She has been a board member at a number of non-profits related to open source and inclusion in tech. At UC Open she will speak to how AI is reshaping open source community building, onboarding, and contribution—drawing on decades of experience sustaining open source ecosystems inside major technology companies.
Yuan-Jiun (David) Sung is the Principal Investigator and Lead Architect for the Open Analytics Control Tower (OACT).

The NSF Pathways to Enable Open-Source Ecosystems (POSE) program has funded a remarkable range of projects across the UC system—each taking a research software project and asking how it becomes something bigger: a sustainable community, a shared resource, an ecosystem. This panel brings together UC-affiliated POSE principal investigators to reflect on that journey. Panelists will share what their projects do, who their communities are, how POSE funding changed their approach, and what sustainability looks like beyond the grant—followed by open discussion about the lessons, surprises, and hard-won wisdom of building open source at a research university.
