Systems Biology

Definition

Systems biology is an interdisciplinary field that focuses on the complex interactions within biological systems, integrating data from genomics, proteomics, and metabolomics to understand how these systems operate as a whole. By applying mathematical modeling and computational approaches, systems biology aims to reveal how various components of a biological system work together to influence health, disease, and treatment responses.
