WEEKLY COMMUNITY CALL MEETING
Join us Tuesday, Nov. 25 (11 am ET) for an OHDSI community call dedicated to highlighting and supporting our early-stage researchers. The Early-Stage Researcher Workgroup—now led by Harry Reyes Nieva, Benjamin Martin and Shounak Chattopadhyay—will share their mission, priorities, and new opportunities to get involved.
We’ll also spotlight three Global Symposium presentations that earned top evaluations among early-stage researcher submissions, with the project leads joining to share their work:
• Sumin Lee and Kyulee Jeon (Yonsei College of Medicine)
• Markian Hromiak and Jacob Zelko (George Institute of Technology)
Exploring Efficient and Scalable OMOP CDM Workflows by Leveraging dbt-synthea
• Bingyu Zhang (University of Pennsylvania)
Everybody is invited. If you do not have a calendar invite, please use this link to join the meeting. All recordings from these weekly calls are available within our Teams environment and will be posted on both our YouTube page and our OHDSI.org Community Calls page.

OHDSI UPDATES
The 12th annual OHDSI Global Symposium will return to the Hyatt Regency Hotel in New Brunswick, N.J., Oct. 20-22, 2026. All pertinent information will be added to this page when available. Currently, the OHDSI steering group is seeking proposals for both plenaries and tutorials. The deadline for both is January 30, 2026; more details are available on the event homepage.
• There is a new tutorials homepage on OHDSI.org that hosts all tutorials from past Global/US Symposia, including all six tutorials from the recent Global Symposium.
• The latest Our Journey annual report is now on the OHDSI homepage. This 134-page PDF provides an overview of the OHDSI community, including a look at its collaborators and collaborative activities, its research areas and tools, its work with standardized data and vocabularies, and nearly 900 publications that have come from the community.
• Registration is now open for the 2026 Summer School in Observational Health Data Science & Informatics, AI, and Real World Evidence, which will be held June 22-26 at the Columbia University Department of Biomedical Informatics. Now in its second-year, the Columbia OHDSI Summer School provides health professionals, researchers, and industry practitioners with an immersive, hands-on training to working with real-world health data and generating real-world evidence (RWE). Participants will explore the types of healthcare data captured during routine clinical care—such as electronic health records and administrative claims—and learn how to standardize these data using the OMOP Common Data Model to support collaborative, distributed research as part of a data network.
OHDSI Social Showcase
• Research from the 2025 Europe Collaborator Showcase is being shared daily on OHDSI’s LinkedIn, Twitter/X, Instagram and Bluesky social channels as part of the #OHDSISocialShowcase. Below are posters (with study leads) that are featured this week:
Monday — The potential of LLMs for multilingual NER in clinical notes (Sara Mazzucato)
