ALT In this hands-on workshop, we will start with a simple example and build it up step by step, using each extension to introduce a new idea and show why it matters.We will use Stan to fit models while developing intuition for priors, likelihoods, posterior inference, prediction, and model checking. We will spend time working directly with posterior draws: understanding what they represent, using them to estimate parameters, and answering questions from fitted models. From there, we will extend the example to hierarchical modeling and see how partial pooling works and when it can be useful.The focus will be on understanding the modeling workflow and the choices we make along the way. Participants should leave with a practical understanding of Bayesian inference, experience fitting models in Stan, and a clear path for applying these ideas in their own work.

ALT {teal} is an innovative open-source R-Shiny framework that has transformed how clinical trial data is analyzed and visualized in recent years. By streamlining the creation of interactive web applications, it enables R programmers and data scientists to deliver insights faster while promoting efficiency, transparency, and reproducibility in data exploration. This hands-on workshop, built on the latest {teal} 1.0 release, will start from the basics and progressively cover practical topics for building {teal} applications. Together, we will explore key features of {teal} and work through step-by-step exercises designed to build confidence and proficiency in {teal} programming. No prior experience with {teal} or attendance at previous workshops is required - all R users are welcome. Designed to deepen participants’ understanding of the {teal} framework, this session will equip attendees with the skills to leverage the {teal} ecosystem to create scalable, reproducible applications that acce

ALT GSK’s journey to Clinical Study Reporting Using Open Source GSK’s Journey to Clinical Study Reporting Using Open Source chronicles the transformation of clinical reporting at GSK, the presentation marks pivotal moments in the pharmaceutical industry’s evolution—from the proprietary, SAS-dominated era of the 1980s and 90s, through the pain of rising R&D costs and global health crises, to the emergence of collaborative models and open-source innovation. The story highlights how industry challenges catalyzed a shift toward openness and collaboration. Key milestones include the FDA’s clarification on software neutrality, the rise of R and open-source platforms, and GSK’s commitment to writing at least 50% of code in open-source languages. The COVID-19 pandemic accelerated this transformation, driving rapid adoption of data science platforms and collaborative tools. GSK’s multi-wave approach to change is shared and candidly addresses ongoing challenges: technical validation, regulatory un

ALT The number of workflows and tools leveraging large-language-models (LLMs) is growing exponentially across the world, and the life sciences industry is no exception. In this session, Eric Nantz takes the role of the curious and savvy data scientist as he is joined by Posit CTO Joe Cheng in a special live demonstration on using Databot to power an exploratory data science analysis. Throughout the demonstration, Joe will share the fascinating origin story of how Databot came to be, along with a deeper conversation on the recent trends and guiding principles of harnessing AI tools for data analyses and software engineering. This interactive, spontaneous format will allow the audience to submit questions and steer the direction of the session, making it a truly engaging, shared experience.
