Congratulations to the team of Nigel Hughes, Peter Rijnbeek, Kees van Bochove, Talita Duarte-Salles, Carl Steinbeisser, David Vizcaya, Dani Prieto-Alhambra, and Patrick Ryan on the publication of Evaluating a novel approach to stimulate open science collaborations: a case series of “study-a-thon” events within the OHDSI and European IMI communities in JAMIA.


Northeastern University invites applications for multiple tenured/ tenure-track faculty positions in support of an Impact Engine centered on large-scale observational health data science and informatics to start in the fall of 2023. These faculty will be core members of our Real-World Healthcare Navigator (RWHN) Impact Engine which aims to change how research is translated into clinical practice by establishing a sustainable service that leads the way in fully reproducing health studies (Real-World Healthcare Navigator | Impact Engines). Successful candidates will work closely with the OHDSI Center at Northeastern’s Roux Institute to develop and apply healthcare analytics in the real-world evidence (RWE) area with the goal of improving patient health outcomes. More information and an application link are available here.

 The OHDSI Center at the Roux Institute seeks a postdoctoral fellow to join their team focused on developing statistical methods and applying them to observational data from large-scale federated datasets (e.g. electronic health records and administrative claims data), with specific applications to the safety of biologics. This research will directly improve our ability to use real world data to characterize patient populations, construct population level estimates relating exposures to health outcomes, and to enhance clinical decision making through improved patient-level predictions. More information and an application link are available here.

 FDA/CDER’s Division of Hepatology and Nutrition is seeking a clinician with bioinformatics or biostatistics training to work with the Drug-Induced Liver Injury (DILI) Team to evaluate large datasets of liver-related data, collaborate on the Team’s review of drugs with hepatotoxicity signals, and help develop informatics-based processes in DILI evaluation across the Agency. Contact Judy Racoosin at judith.racoosin@fda.hhs.gov for information about the application process (that will be through USAJOBS).

• Andrew Williams recently announced two exciting new openings at Tufts Medicine. 1) Senior Project Manager for a multisite multiyear grant standardizing critical care EHR and waveform data. (CHoRUS Bridge2AI) 2) Lead software developer and research data warehouse manager for Tufts Medicine’s OMOP instance and related services. Remote work is possible for both positions. If you have questions, please reach out to Andrew at awilliams15@tuftsmedicalcenter.org.

 The Johns Hopkins OHDSI team has just put out an opening for a data scientist/statistical engineer position. The candidate is expected to help create further synergy between the domain expertise of Johns Hopkins’s Precision Medicine Centers of Excellence and the extensive health data network provided through our OHDSI collaboration. More details and an application link are available here.


The EMA has selected the first 10 data partners to collaborate with DARWIN EU®, the Data Analysis and Real-World Interrogation Network. The data available to these partners will be used for studies to generate real-world evidence that will support scientific evaluations and regulatory decision making, and all have already been mapped to the OMOP CDM. You can learn more about how OHDSI is collaborating with DARWIN EU®.

• The next OHDSI APAC Community Call will be Dec. 1 (Nov. 30 in the Western Hemisphere) and will recap the APAC Symposium. You can join these bi-weekly community calls here.

• Patrick Ryan introduced the OMOP Common Data Model (CDM) Entity-Relationship Diagram (ERD) Challenge on the forums recently. All members of the OHDSI community are welcome and encouraged to submit their entries of the best ERD for the OMOP CDM to this forum post (or to the CDM Workgroup MS Teams site) by Tuesday, Dec 13. One winner will be selected by a committee from the CDM workgroup, and announced on OHDSI’s last community call of the year on Dec 20.

• Anna Ostropolets will defend her dissertation at Columbia University on Wed., Nov. 30, with an open session scheduled for 10 am ET (join that session here). Her dissertation title is “Generating Reliable and Responsive Observational Evidence: Reducing Pre-analysis Bias.”

• Rupa Makadia was the latest guest to join the Early-Stage Researchers Career Speaker Series. You can watch that discussion here. The next session will be held Monday, Dec. 12 (11 am ET), and Kristin Kostka will be the featured speaker. You can join the call at https://bit.ly/OHDSILeaders.
