Systems Biology Core Laboratory

Comprehensive understanding of normal physiology, disease-associated alterations and recovery following a treatment requires synergizing “omic” and pathophysiological data to identify and quantify the molecular mechanisms responsible for patient outcomes. By quantifying thousands to millions genomic characteristics at a time the microarray and next generation sequencing technologies offer the opportunity to understand the biological system as a whole. SBC combine the theoretical and experimental skills of two faculty members to provide resources and expertise to design, perform, understand and analyze a wide variety of pathophysiological and “omics” studies.
