Biomarker Discovery
Developing reliable biomarkers can guide drug development decision-making. The application of statistical and machine learning techniques to large datasets from varied sources can assist the process of biomarker identification. Once identified, these biomarkers can be applied to population enrichment strategies and precision medicine.
