The Vocabulary Team - OHDSI/Vocabulary-v5.0 GitHub Wiki

Find below the members of the OHDSI Vocabulary Team, including the core team at Odysseus-EPAM. These are the people who take care of the OHDSI Standardized Vocabularies that you can download from ATHENA. Except for Aliaksei, who is a professional developer and database administrator, the vocabulary team consists of medical professionals with a profound knowledge of medical informatics and terminology.

Name	github handle and email	Area of Expertise
Anna Ostropolets	aostropolets [email protected]	Anna leads the Vocabulary Working Group & pushes Vocabularies Improvement Initiative together with the Team. She also contributes to the drug space. Want to complaint about RxNorm Extension or ATC? Find her on Forums or Teams.
Masha Khitrun	m-khitrun [email protected]	Masha is a technical lead of the team and a passionate explorer by nature. She has a unique expertise and deep knowledge of vocabulary development, and orchestrates the release-related activities. If you have any questions related to the technical implementation of your terminology in the OHDSI ecosystem, Masha is the right person to ask.
Alexander Davydov	alexdavv [email protected]	Alexander is the Community Contribution lead and a go-to person to include your local or national vocabularies to Athena. He was the Vocabulary Team and Technical Lead from 2018 to 2024. The ontology world needs more Alexes to be a better place!
Vlad Korsik	vladkorsik [email protected]	Vlad is ex-Vocabulary Team Lead (2025). He is the master of Oncology concepts and takes a fair share in making Genomic vocabularies available. He also knows everything about caveats of mapping your source vocabularies and data into OMOP CDM and OHDSI Standardized Vocabularies. Wake him up at night (please, don't!), and he will tell you all about mappings and data standardization.
Oleg Zhuk	TinyRickC137	Oleg is the ex-Vocabulary Team and Technical Lead (2023-2025) and is currently providing consulting and mentorship help for the team. Currently, Oleg is leading the initiative to harmonize the Procedure domain and create a clear, concise hierarchy.
Aliaksei Katyshou	AlaikseiKatyshou	Aliaksei maintains most of the logic that does the heavy lifting in vocabulary source ingestion and technical processing. Loops? Errors? Bugs? Turn 100 lines of code into 5? He got you.
Mikita Salavei	MSalavei	Mikita has special expertise in the MedDRA classifications and their connections to SNOMED. He is also interested in new approaches for mappings (stay tuned for new discoveries!).
Maria Rogozhkina	MariaRohozhkina	Maria chose the measurements and is an expert in LOINC now, but also helps maintain the vaccines (are we over COVID-19 yet?). She likes playing with hierarchies and complex cases (have you checked out the new smoking hierarchy yet?).
Varvara Savitskaya	varvarenius	Varya has taken over large parts of the Genomic vocabularies processing. Like a recent VANDF release? Thank her!
Tetiana Orlova	TetianaOrlova	Tetiana specializes in neurology and is deeply involved in ETL projects and custom mapping. She leverages her knowledge to optimize data processes and improve solutions, ensuring efficient and reliable mappings.
Tatiana Skugarevskaya	TatianaSkugarevskaya	Tatiana specializes in psychiatry and plays an active role in ETL processes. She utilizes her expertise to enhance data integration and ensure that medical data is accurately represented and maintained.
Dmitry Dymshyts	dimshitc	Dmitry was the Vocabulary Team and Technical Lead for about 8 years when the system got tremendously expanded to more than 100 vocabularies. Currently, he helps the team to stress test the Vocabularies from the user perspective and suggests on conceptual and strategic decisions.
Christian Reich	cgreich	Christian is the godfather of all OHDSI Vocabularies (and yes, that Mob-reference is still lingering in the air). He is your guy to discuss tricky questions.
