Research Interests

  • Ovarian cancer
  • Evolutionary biology and ecology of various organisms

Current Research

Currently I am using molecular tools in an attempt to understand the molecular biology of ovarian cancer, particularly the microenvironment of the cancerous cells. Instead of using bulk tumor tissue that is a heterogeneous collection of cells, I use laser capture microdissection to dissect only the cells of interest (i.e., only cancer cells or only stromal cells).
