Current Research Interests
My research focuses on various aspects of interoperability of biomedical data, including terminologies and ontologies, derived artifacts, such as value sets, and clinical datasets, using Semantic Web technologies. I have developed a framework and workflows based on terminology integration systems, such as the UMLS and RxNorm, to analyze and compare value sets used for clinical quality measures. More recent applications include analyzing co-prescription data in electronic health records from the perspective of drug-drug interactions, alignment and comparison of drug information sources, and extraction and characterization of drug adverse events from MEDLINE indexing.
