Research Interests

Having a background in fluid mechanics and cell mechanics, Professor Ryu has research interests in investigating multiscale flow systems and biological systems based on interdisciplinary experimental approaches.

Research interests in flow systems include 1) interfacial dynamics of bubble, drop and foam, 2) fluid flow at finite Reynolds numbers, 3) microfluidics, 4) fluid dynamics of microorganisms, and 5) flow-system-based sustainable energy technology.

Research interests in bio systems include 1) calcium-powered cell motility and its biomimetic application, 2) mechanobiology of stem cell differentiation, and 3) cellular mechanics of cancer cells.
