Specific combinations of genes exhibit emergent properties when expressed together, enabling the generation of diverse cell types and behaviors. This phenomenon motivates the quantitative study of genetic interactions (GIs), which compare the phenotypic consequences of perturbing two or more genes alone or in combination. The challenge of studying GIs is their sheer scale: e.g., among 10,000 genes there are ~50 million possible pairwise GIs. The Norman Lab blends computational approaches with high-throughput experimental methods to develop new screening approaches for finding and characterizing genetic interactions.
