Dr. Carter works closely with Boston area physicians to design and execute studies of cancer initiation, drug resistance, and metastasis using genomics technology applied to cancer-tissue specimens collected at various stages of disease progression. Dr. Carter has developed several novel computational methods in order to analyze these datasets and make inferences about clonal evolution underlying cancer progression. He has also developed software tools that are significantly increasing the impact of his work by making those methods available to the broader research community. These tools include HAPSEG, ABSOLUTE, CapSeg, Allelic CapSeg, and Phylogic.
