Our lab is interested in somatic evolution. We are using a variety of systems-level approaches to study the origins and consequences of somatic variation, blending computational and high-throughput wet lab methods.

Our main focus is carcinogenesis. We are interested in understanding how processes of mutation and selection in normal (stem) cells set the stage for cancer evolution. Then, once a tumor develops, how does tissue-specific selection shape the cancer genome? How can we take advantage of genetic intra-tumor heterogeneity to gain insights into the life history of a cancer?

We are particularly interested in the evolution of metastasis. Do metastases arise from distinct clones with special, genetically encoded properties or do they represent random samples of the primary tumor? Does metastatic spread happen early or late in tumor development? Do all metastases arise independently from the primary tumor, or do they give rise to each other (Science 2017)?

The answers to these questions have important clinical implications, but are difficult to study in human patients because it is challenging to reconstruct occult events that happened years before diagnosis. We have developed genetic techniques (PNAS 2014) to determine the clonal architecture and lineage of cancer cells in human specimens, and collaborate with clinicians in utilizing these tools to further our understanding of cancer evolution.
