Meet the 2017 Faculty

We are proud to announce the faculty for the 2017 tutorial workshops:

 

Rimma Belenkaya, M.A., M.S.
Data Modeler/Knowledge Manager
Montefiore Medical Center

I am a Data Modeler and Knowledge Engineer in the Department of Clinical Research Informatics at Montefiore Medical Center. I am interested in semantic and relational data modeling of bio-medical information, data integration, interoperability of data models, and data quality assurance. My current focus is on integration and quality assurance of electronic health data from heterogeneous sources for institutional performance analysis, translational and comparative effectiveness research, and identifying cohorts for prospective studies.

During the last two years, I have been intensely engaged in the PCORI-sponsored CDRN project that intends to consolidate patient records from multiple medical centers across the country for comparative effectiveness research. Hence, my interest and involvement in the OHDSI community. I worked on the adoption of the OMOP Common Data Model (CDM) as a staging model for the New York City CDRN, establishing interoperability standards between OMOP and CDRN models, and contributing to the development of OMOP CDM and vocabulary. I presented results of these efforts in a poster session and two panels at the 2015 AMIA Join Summits on Translational Science. I along with the OMOP-CDRN interoperability collaborative will be presenting our work at the OHDSI symposium.
