Her background is in both wet and dry lab translational science, with a focus over the past decade on the development of ontologies, semantic engineering technologies, and open science infrastructure programs. Dr. Haendel’s vision is to weave together healthcare systems, basic science research, and patient generated data through development of data integration technologies and innovative data capture strategies. Dr. Haendel co-leads the Monarch Initiative, an international consortium dedicated to utilizing model organism genotype-phenotype data, deep phenotyping, and graph-based integration techniques to improve rare disease diagnosis. She also co-leads the NCATS Data Translator, which aims to integrate hundreds of data resources for mechanism and drug discovery. The CD2H is tasked with coordinating informatics across 59 Clinical and Translational Science Award Institutes, and is focused on implementation of cloud and information architecture, clinical data model interoperability, and precision-medicine focused terminology development. Dr. Haendel is the co-lead for the GA4GH Clinical and Phenotypic workstream, where she supports cross-disciplinary international teams, development of standards for clinical genetics in rare disease and cancer, and improving access to data across the world.
