Welcome to the Bio/Flow Systems Research Lab! Research in our group focuses on investigating flow systems and biological systems based on interdisciplinary multiscale experimental approaches. As "Bio/Flow" in our lab name implies, our research interest is not limited to biological flow systems, and it covers not only pure fluid flow systems ranging from microscale flows to turbulence, but also biological systems ranging from cellular mechanics to animal locomotion. Our final goal is to pursue applications of principles found in biological and fluid dynamic systems in engineering solutions.

Currently we are working on projects on fluid dynamics and cell motility of a stalked protozoa Vorticella and their applications, interfacial fluid dynamics of soap bubble blowing and drop coalescence, mechanobiology of breast stem cells and neuron cells. To tackle our questions, we use experimental tools including flow visualization, microfluidics, high speed imaging, video microscopy, atomic force microscopy, and numerical simulation tools including computational fluid dynamics simulation.
