Mechanotransduction and Biophysical Regulation
In addition to biochemical and biological factors, biophysical cues such as mechanical forces, electrical signals and the micro/nano structure play important roles in cell sensing, signal transduction and epigenetic regulation. Our goal is to elucidate the mechanisms of mechanotransduction and biophysical regulation, and develop technologies to engineer cell fate and tissue regeneration. Ongoing studies include: (1) effect of mechanical factors on cell sensing, 3D genome and epigenetic state, and (2) electrical modulation for neuromuscular regeneration.
