Reproducibility under Pressure: Notebooks, LLM Agents, and the New Computational Stack
Tanu Malik: Associate Professor, Electrical Engineering & Computer Science, University of Missouri-Columbia
Reproducibility is a foundational pillar of scientific computing, yet it faces mounting pressure from two converging trends: the widespread adoption of notebooks for executing large-scale scientific workflows, and the rapid rise of LLMs as autonomous coding agents. This talk examines reproducibility challenges at both ends of the modern computational stack, from notebook-based distributed workflows to LLM-generated code that executes out-of-the-box only 68.3% of the time.

Juliana Freire
Professor of Computer Science and Data Science, NYU. Co-director, Visualization Imaging and Data Analysis Center (VIDA)
Juliana Freire develops methods and systems that enable a wide range of users to obtain trustworthy insights from data, spanning large-scale data analysis, machine learning, provenance management, and computational reproducibility. She has co-authored over 250 technical papers, is an inventor of 12 U.S. patents, and is an NSF CAREER and ACM SIGMOD Contributions Award recipient.
Abstract
The abundance of data, accessible computing power, and storage has revolutionized science and ushered an era of data-driven scientific discoveries. However, this paradigm shift has raised critical questions about how to adapt the scientific process to ensure transparency and reproducibility. In this talk, Juliana Freire will discuss the challenges involved in capturing and managing computational provenance, and examine the evolution of methods and tools that have been proposed to facilitate transparency and reproducibility.
