My laboratory research is focused on deciphering mechanisms of dysregulated signaling in myeloproliferative neoplasms (MPNs). We recently identified novel mutations in the adapter protein LNK, a negative regulator of JAK-STAT signaling, in MPN patients, and ongoing work is aimed at characterizing the functional impact of these LNK mutations on MPN pathogenesis. We utilize phospho-specific flow cytometry to evaluate signaling in MPN patient samples, and are developing next-generation mass cytometry technologies to facilitate high parameter, phospho-proteomic approaches to characterize aberrant signaling at the network level. The ultimate goal is to translate this work into improved therapies for MPN patients.
