Research Summary
We seek to understand the optimization of bacterial proteomes at both mechanistic and systems levels. Our work combines high-precision assays, genome-wide measurements, and quantitative/biophysical modeling. Ongoing projects focus on the design principles of transcription, translation, and RNA maturation machineries in the face of competing cellular processes.Awards
