Current Research Directions

Breast & Ovarian Cancer

Breast & Ovarian Cancer

Breast & Ovarian Cancer

Our research has focused on breast and ovarian cancers - both important causes of cancer-related deaths in women. Our studies look at how molecular differences in cancer cells alter their biophysical properties to promote invasive and chemoresistant cancer cell phenotypes.

Tumor Microenvironment

Breast & Ovarian Cancer

Breast & Ovarian Cancer

We study cell-cell and cell-matrix interactions in the tumor microenvironment to understand how recruited stromal cells, paracrine factors, and modifications in the extracellular matrix contribute to disease progression.

Exosomes & Soluble Cues

Breast & Ovarian Cancer

Polyploidal Giant Cancer Cells

Several projects focus on cell secreted growth factors and exosomes that mediate cell signaling processes in the tumor microenvironment. Exosomes are cell-secreted nanovesicles that transfer RNA and protein to other cells. Their stable membranes are decorated with receptors that allow for tissue homing.

Polyploidal Giant Cancer Cells

Polyploidal Giant Cancer Cells

Polyploidal Giant Cancer Cells

Our recent work has focused largely on PGCCs. PGCCs are large and often multinucleated  non-dividing cancer cells that are resistant to chemotherapy and radiation treatment and give rise to daughter cells through budding.

Metabolism & Autophagy

Polyploidal Giant Cancer Cells

Metabolism & Autophagy

The tumor microenvironment is under stress from nutrient deprivation, tissue hypoxia, and chemotherapy which alters cell metabolism to promote cell survival. Our work has focused on metabolic adaptations in ovarian cancer cells which give rise to chemoresistant cells.

Senescence & Cancer

Polyploidal Giant Cancer Cells

Metabolism & Autophagy

Our work has focused on senescent cells that accumulate in normal tissues and tumors and alter the tissue microenvironment to promote disease progression through their SASP and SA-ECM modifications.

Radiation Induced Fibrosis

Heterogeneity in Cancer Cells

Heterogeneity in Cancer Cells

Age and radiation induced senescence increase TGF-beta expression to promote ECM remodeling and lung fibrosis. Projects use multiphoton imaging to characterize changes in the ECM at multiple length scales.

Heterogeneity in Cancer Cells

Heterogeneity in Cancer Cells

Heterogeneity in Cancer Cells

Heterogeneity analysis in cell phenotypes is used to identify outlier populations of invasive cells.  This small population of invasive cells is likely representative of invasive cell types that exist in more physiological tumor environments.
