Research Interests
My research interests focus on 1) quantifying spatial and temporal dynamics of proteins during cell migration and
2) developing novel imaging technologies. 

Cell migration is vital for embryonic development, wound healing, and cancer metastasis. We are using the cutting edge biophysical tools to monitor molecular interactions in live cells and how their activity in spatial locations mediates cell migration. Using the raster image correlation spectroscopy (RICS) method and the Number and Molecular Brightness (N&B) analysis we have revealed the dynamic assembly and disassembly of focal adhesions as well as determined the aggregation and stoichimonetry of protein interaction. In particular we are investigating tumor invasion and executing a strategy to monitor signaling for cells migrating in 3D matrices and in tissues.
