Training Group(s):
Chromatin and Regulation of Gene Expression

Active Mentor - currently hosting PULSe students for laboratory rotations and recruiting PULSe students into the laboratory; serves on preliminary exam committees

Current Research Interests:

The overarching goal of our research is to elucidate epigenetic mechanisms that control cell identity and determine how these mechanisms are disrupted in cancer. The research specifically focuses on the activity of distal regulatory elements, called enhancers, and insulators of developmental genes by using mouse embryonic stem cells and embryonal carcinoma cells as model systems. In addition, we also study biochemical mechanism/s of DNA methyltransferases and the effect of mutations commonly found in cancer and other developmental disorders.
