United by this mission, PierianDx’s team of dedicated medical professionals, scientists, genomics experts and developers help our customers advance precision medicine by simplifying the process of turning DNA into actionable clinical insight.


A Legacy of Innovation

Through the completion of the Human Genome project to 2011, our founder Rakesh Nagarajan led a multi-disciplinary team of scientists, bioinformaticians, engineers, and biostatisticians at Washington University in St. Louis to solve a problem – handling and integrating the vast amounts of clinical and translational research data and turning it into actionable insights. This data included medical records, clinical trials, patient registries, biospecimen repositories, and genomics data generated from Next Generation Sequencing (NGS). In 2011, Rakesh and his team set their sights on solving this problem clinically and invented one of the first clinical bioinformatics platforms in the industry capable of enabling labs to perform NGS testing. Since spinning out of Washington University in 2014, PierianDx has extended the capability of its knowledgebase and clinical workflow, building one of the most comprehensive clinical genomics platforms in the industry. Today, health systems, academic medical centers, cancer centers and children’s hospitals worldwide are using PierianDx’s Clinical Genomics KnowledgeSpace™ and WorkSpace™ to advance precision medicine.




By becoming a PierianDx customer you join an expanding list of precision medicine leaders who contribute to one of the most extensive knowledgebases in the industry. By sharing medical interpretations, variant classifications, and aggregated variant and clinical data, each customer added to the PierianDx community expands the intelligence of the PierianDx Clinical Genomics KnowledgeSpace™. PierianDx’s knowledgebase is comprehensive database containing millions of biomedical findings that are constantly updated. Join the growing team of health systems, academic medical centers, cancer centers, children’s hospitals and commercial labs who have turned to PierianDx for a complete solution to their NGS testing needs.
