Description of Research Expertise
Research InterestsMolecular mechanisms of cell motility
Key words: Cell motility, myosin, actin, biochemistry, single molecule, spectroscopy, microscopy, fluorescence, nanotechnology.
Description of Research
The goal of our research is to understand the molecular mechanisms of cell motility, which include: cell migration, regulation of cell shape and extracellular attachment, and intracellular transport. Cell motility is crucial for several normal and pathological processes, including: cell and tissue development, endocytosis, wound healing, immune response, and metastases of tumors.
