Associate Professor of Biomedical Informatics
Columbia University

Dr. Elhadad’s research is in biomedical informatics, natural language processing, and data mining. I develop techniques that aim to support clinicians, patients, and health researchers in their information workflow by automatically extracting and making accessible information from unstructured, large clinical datasets (e.g., the electronic patient record), patient platforms (e.g., online health communities), and quantified self. My research relies on two types of methods: (1) I design novel computational approaches that infer models of health phenomena and account for the specific biases of large health data; (2) I translate the learned models into actionable knowledge and robust systems within the healthcare ecosystem (e.g., a patient record summarization system for clinicians at the point of care). Current projects include patient record summarization and large-scale probabilistic phenotyping based on clinical records, building shared annotated lexical resources (ShARe) for clinical natural language processing, and building tools to facilitate content analysis of online health communities. Dr. Elhadad is part of the OHDSI NLP Working Group.
