She conducted groundbreaking research using high-throughput genomic technologies to understand the immune mechanisms that lead to graft injury and loss. Importantly, she aimed to identify gene expression profiles or genetic variants that would predict patients' risk for disease."

"Dr. Murphy's laboratory took a systems biology approach to identify genetic drivers of fibrosis; this had important implications for kidney transplantation, but she hoped it would have an enormous impact on all organ transplantations in the future."
