Research Summary

We use biochemical and live cell biosensor imaging approaches to study cellular energetics during epithelial-to-mesenchymal transition and cancer cell motility through extracellular matrix and 3-D microfluidic environments. Altering the physical environment of cells through increased confinement can change the energetic demands involved in migration, and result in different activation and requirements for metabolic pathways. In cancer, the normal regulatory responses that control cell metabolism are often disrupted, so we are also interested in determining whether the migratory behavior of metastatic cancer cells results in increased susceptibility to therapies targeting metabolic pathways.
