Dr. Ratnesh Sahay

Head of Research Unit

Insight Centre for Data Analytics, NUI Galway, Ireland




I am passionate about connecting variety of data (graph, images, key-value, stream , table, text, tree) and retrieve such interconnected data in a manner that:


  •   ♦   Enables quality and accurate predictions over healthcare and biomedical datasets

  •   ♦   Utilises the multi-dimensional connectivity of data as knowledge graphs

  •   ♦   Allows querying and traversal of information across distributed data end-points

  •   ♦   Extracts actionable knowledge from healthcare and biomedical predictive models

I am interested in developing technologies that can ease the access of interconnected healthcare (phenotype) and genomics (genotype) data which will ultimately bring precision medicine into the clinical use. I approach towards the precision medicine from a data (computational) perspective. I have always believed that the human health and disease is one area which can immensely benefit from connecting the vast pools of data ecosystems (electronic health records, clinical trials reports, genetic discoveries, climate and environmental changes).


Specialties: Electronic Health Records (EHRs), Clinical Trial Databases, Cancer Genomics, Linked Data, Ontology, Knowledge Graph & Data Analytics.
