Scientific Activity

Our long-term interest is in understanding the regulatory parameters that influence the outcome of an immune response. Within this our current focus is to understand the mechanisms controlling plasticity in receptor-initiated signaling pathways. The experimental strategy involves a ‘systems level’ analysis of the antigen receptor-dependent signal transduction network. We measure the kinetic and quantitative contributions of various intermediates in the signaling pathways and then monitor how these contributions are modulated in response to specific perturbations within the network. Our larger goal is to delineate the overall structure of this network and also to characterize its dynamic features. We are particularly interested in deriving both quantitative and qualitative measures of signal output under conditions where the receptor is differentially activated. The aim here is to eventually understand how such information processing impacts on the gene expression profile.
