Research Summary

Next-generation sequencing technologies developed in the last ten years have dramatically widened our view into the many kinds of events that are driving tumor biology. Gene fusions, copy number alterations, mutations, epigenetic changes, stromal microenvironment, immunogenicity and transcript level alterations can all be ascertained via the knife of DNA and RNA sequencing. Statistical methods, factor analysis, insights from evolutionary biology and immunology as well as an understanding of mutation processes at work in tumors can help us distill out the important driver events from the background of non-functional passenger mutations, and give us useful insights into the multiple systemic processes driving tumor progression.

I am specifically interested in using these integrated approaches to help understand and improve treatments for gynecologic cancers. However, the "organ of origin" approach has narrowed our view and exploring carcinogenesis pan-cancer will allow for novel insights into uncommon or difficult to treat gynecologic cancers. To this end, I collaborate with clinicians and scientists across oncology with a goal to further a model of cancer medicine in which genetic data is incorporated.
