Our lab focuses on how regulation of gene expression is directly executed by the ribosome, particularly in the innate immune response. Our lab studies a fundamentally new mode of gene regulation by which ribosomal RNA (rRNA) regions exposed on the outer shell of the ribosome bind to selective transcripts to control mRNA- and species-specific translation. We combine innovative RNA biochemistry and RNA-based technology development with model systems ranging from yeast to macrophages. Our ultimate goal is to decipher how rRNA-directed specialized translation shapes gene expression to understand the role of the ribosome in innate immune responses.
