July 8th - 10th, 2026 (virtual) - This workshop introduces participants to the GastroPlus® API and demonstrates how it can be used to streamline both basic and advanced modeling workflows. Through practical, hands-on examples, attendees will learn how to automate routine tasks, customize reports, manage in silico experimentation workflows, and leverage advanced API capabilities to improve efficiency, reproducibility, and scalability in PBBM-PBPK modeling projects. GastroPlus® Summer School: Practical API Skills for Basic and Advanced Modeling  Better, Faster, Stronger: Accelerating PBBM-PBPK Workflows with the GastroPlus® Application Programming Interface (API) Free Online Training | July 8 - 10, 2026 Choose 8:00AM - 10:00AM Pacific or 9:00AM - 11:00AM Central European Why This Training Matters The PBPK Summer School is designed for modelers who want to learn how to extend and accelerate their PBBM–PBPK workflows using the GastroPlus® application programming interface (API) in R. Across three intensive sessions, participants will learn how to integrate observed data into a GastroPlus project, generate automated reports, run multiple virtual populations simultaneously, and execute high-throughput PBPK studies. Previous knowledge of R is not mandatory.  More than a software tutorial, this course provides the framework, practical skills, and mindset needed to support advanced modeling applications and inform regulatory decision-making. You'll discover not only how to use the novel GastroPlus® API, but also why its functions must be executed in a specific order to support your PBBM-PBPK modeling workflow. With hands-on exercises, live expert guidance, and a free temporary GastroPlus® license, you'll be able to experiment directly on your own projects and bring back immediately usable workflows to your team. How You Will Learn Live, online lecture led by GPX™ experts each day Learn directly from the people who develop and use the tools at the highest level, gaining not just instructions but insight into best practices, strategies, and real-world applications. Two identical 2-hour sessions per day - choose the time zone that fits you - and video recordings Ensure you can participate live, ask questions, and learn at your best time without missing content or interaction. Interactive Q&A chat during each session with GPX™ experts Get immediate answers to your modeling challenges and clarify concepts as you learn, turning lectures into active problem-solving sessions. Hands-on exercises to reinforce new skills Apply what you've just learned in a guided environment, moving from theory to practice and cementing your ability to replicate these workflows later. Comprehensive materials: presentations, datasets, and GPX™ projects Build your own reference library to revisit concepts, test workflows on your own time, and accelerate mastery after the course Certificate of Attendance Demonstrate your training in advanced PBPK and GPX™ to colleagues, supervisors, or regulatory bodies. Free temporary license for GPX™  Use the same tools you're learning on your own projects, experiment with advanced features, and get immediate help from experts during the course - turning learning into direct project impact. Skills and Insights You'll Gain Session 1: Introduction to the GastroPlus® API Session 2: Predicting and Reporting Midazolam Pharmacokinetic Changes in Pediatric Populations Using the GastroPlus® API Session 3: High-Throughput PBPK Simulations Using the GastroPlus® API Read more
