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 2022 Asia-Pacific (APAC) Symposium was held Nov. 12-13 at the Taipei Medical University in Taiwan. There were both in-person and remote components to this event, including tutorials on Nov. 12 and the main conference on Nov. 13. Thank you to our APAC leadership team for putting together this event.

• Videos and slides from both the main day and the full-day tutorial at the 2022 OHDSI Symposium have now been posted.

• Do you represent a healthcare system that has adopted OMOP? The Healthcare Systems Interest Group is gathering evidence to support additional healthcare systems’ adoption decisions, and the workgroup wants to hear about the benefits your organization has realized. Please take this survey!

OHDSI Social Showcase

 The #OHDSISocialShowcase begins this week, as all the research from the OHDSI Symposium collaborator showcase will be presented on the Twitter and LinkedIn social feeds over the next several months. You can see the research and the respective leads that will be shared this week.

Monday: Deployment of an OMOP CDM-compatible NLP system for Rapid Development and Dissemination of a Long-COVID Extraction NLP task (Andrew Wen)

Tuesday: Impact of random oversampling and random undersampling on the development and validation of prediction models using observational health data (Cynthia Yang)

Wednesday: Building Korean NER models for a manually annotated corpus from clinical notes using cross-lingual transfer learning (Jianfu Li)

Thursday: Protocol for finding supplemental oxygen data in electronic health record (EHR) flowsheets for inclusion in the OMOP ETL (Tanner Zhang)

Friday: COVID-19 Vaccine Administration Pathways in US Administrative Claims (Kevin Haynes)
