Luisa Cochella

One of the main goals of developmental biology is to understand how the different cell types that constitute a multicellular organism are specified during its development. We are currently exploring the different mechanisms of gene expression regulation that control this process. We are interested in how the transcriptional history of a cell influences its fate as well as in how post-transcriptional mechanisms contribute to the diversification of the genetic programs that control cell differentiation.
