Research Focus

My lab investigates how the vertebrate embryonic body plan becomes established and how positional information controls organ development and disease susceptibility. One of our particular interests is the role of left-right patterning in mammary gland development and breast cancer. Using in vivo and in vitro mouse models, we have been the first to show that mammary glands have baseline differences in cellular and molecular composition that are left-right independently regulated during normal and neoplastic development. Furthermore, we have found that the left-right differences identified in mouse models are predictive of breast cancer patient survival, suggesting that tumor laterality plays an important but underappreciated role in disease progression and outcome. Our most recent work focuses on epigenetic regulation of mammary stem cells and how this relates to left-right differences that arise during mammary development and mammary oncogenesis.
