Gene-Wei Li

Gene-Wei Li is an Associate Professor of Biology at the Massachusetts Institute of Technology, serving as Associate Department Head and Director of Scientific Operations in Building 68. Li is also an Investigator at the Howard Hughes Medical Institute. Their research focuses on understanding how bacterial genomes encode and extract precise proteome composition through mechanistic and systems-level approaches. The work integrates high-precision assays, genome-wide measurements, and quantitative modeling to explore the design principles of transcription, translation, and RNA maturation processes. Li's research addresses the optimization of bacterial proteomes in the context of competing cellular processes.

Gene-Wei Li's research focuses on quantitative biology and biophysics, with an emphasis on understanding molecular processes in living cells. His work explores dynamic imaging of genomic loci, single-molecule analysis of proteomes and transcriptomes, and the regulation of transcription and translation. Li investigates how cellular resources are allocated, the role of translational pausing, and the mechanisms of protein synthesis and degradation. His studies also examine the impact of macromolecular crowding, DNA looping, and mRNA structure on gene regulation. By combining advanced imaging and single-molecule techniques, Li's research provides insights into fundamental biological processes at the molecular level.
