WEEKLY COMMUNITY CALL MEETINGS
OHDSI workgroups present opportunities for all community members to find a home for their talents and passions and make meaningful contributions. We continue our 2026 spotlight series during our May 26 (11 am ET) community call as we focus on the Vocabulary WG and the Evidence Network WG. We will hear about all aspects of both teams, including mission, past accomplishments, current research, and future goals, and provide time for conversation at the end.
We are thrilled to welcome lead Anna Ostropolets (Vocabulary) and Clair Blacketer (Evidence Network) to lead this session.
Reminder: The deadline to submit your brief report for the 2026 Global Symposium is June 5 at 8 pm ET. Learn more and find the abstract submission form.
Everybody is invited. If you didn’t receive a call invite, please use this link to join. The call schedule and previous recordings can be found on the community calls page.

OHDSI UPDATES
There are 11 DAYS REMAINING before the deadline to submit your brief report(s) for the 2026 Global Symposium Collaborator Showcase. All information is available here, and you can submit your reports here. The deadline to submit your brief report(s) for the Collaborator Showcase is June 5 at 8 pm ET.
• The FALCON (Federated Alliance for Large-scale Cancer Observational Network) Research Network is dedicated to advancing real-world evidence in oncology by running federated health analyses end-to-end on the OMOP Common Data Model. To drive these efforts forward, the network is hosting the 2026 FALCON Symposium and Bladder Cancer Studyathon from September 28 to October 1 at Dunden in Antwerp, Belgium. This intensive four-day event kicks off with a general symposium and follows with a collaborative, three-day working session designed for researchers, clinicians, and data scientists to generate high-quality clinical evidence.
• Take your OMOP CDM from implementation to impact with The OMOP Practitioner, an intensive three-day expert training hosted Sept. 7-9 by Erasmus MC in Rotterdam. This hands-on program moves beyond the basics, offering a maximum of 30 participants deep-dive experience with the Data Quality Dashboard, ATLAS, and real-world study execution. You will leave with the advanced expertise needed to ensure your data is analysis-ready and capable of generating the reliable evidence required to drive organizational adoption.
• 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.
Job Openings
• The Department of Biomedical Informatics at Columbia University is seeking a highly motivated data science engineer to support large-scale observational research within the OHDSI network. This role will focus on the design, implementation, and execution of distributed network studies using electronic health record (EHR) and administrative claims data to generate real-world evidence. The successful candidate will contribute to characterization, population-level estimation (causal inference), and patient-level prediction analyses across multi-institutional data networks. This position offers a unique opportunity to work at the intersection of biomedical informatics, data science, and clinical research within a leading academic medical center. This position is a full-time two-year position with a possibility of an extension, contingent on available funding.
