About

Sadhna Phanse is a computational biologist whose research centers on microbial systems biology, functional genomics, and the genetic architecture of model organisms. Her most influential work, the 2008 paper "eSGA: E. coli synthetic genetic array analysis," has garnered over 250 citations and introduced a high-throughput method for systematically mapping genetic interactions in *Escherichia coli*. This technique, analogous to synthetic genetic array (SGA) analysis in yeast, enabled researchers to probe the functional relationships between bacterial genes on a genome-wide scale, revealing how combinations of mutations produce unexpected phenotypes. By adapting this powerful screening tool to a prokaryotic system, Phanse provided a foundational resource for understanding bacterial gene function, pathway redundancy, and the genetic basis of antibiotic resistance. Her contributions have been instrumental in advancing the field of microbial genetics, offering a scalable approach to dissect complex genetic networks. Beyond this landmark study, her work continues to inform efforts in systems biology, where she combines computational analysis with experimental validation to uncover the organizational principles of cellular networks.
