Our Research interests
Our research aims to elucidate the mechanisms by which cancer cells spread through the body.
Cancer is a leading cause of death worldwide and accounts for 8.2 million deaths per year.
The formation of metastases is responsible for 90% of deaths in patients with solid tumors.

Our research aims to elucidate the molecular mechanisms by which cells move.
Cell migration is a fundamental physiological process involved in embryonic development, tissue homeostasis, immune surveillance, and wound healing.
For cells to migrate, they must interact with their environment using adhesion receptors, such as integrins, and form specialized adhesion complexes that mediate responses to different extracellular cues.

Our research aims to unravel how cells can sense their environment.
Filopodia are actin-rich “antenna-like” protrusions that are responsible for constantly probing the cellular environment.
In cancer cells, filopodia contribute to single cell migration and invasion, and filopodia-like structures have been implicated in cancer cell survival at metastatic sites.

We use multiple types of microscopy approaches in our work and continuously develop tools to analyze images.
