The Multiscale Fluid Engineering Lab at Korea University aims to study multiscale fluid mechanics and applications.
Our research includes developing bio-inspired advanced fluid management technology and investigating transport phenomena in microfluidic system.
We also develop advanced flow field measurement technologies for investigating industrial flow phenomena and revealing hydrodynamic secrets of nature.

Water Purification Technology
Clean water is in many places a scarce resource and efficient schemes to purify water are in great demand. We develop novel methods for securing fresh water.

Bio-inspired Technology
All living organisms have an optimized survival strategy by adapting to the natural environment. We reveal the hydrodynamic survival strategy of animals and plants and develop bio-inspired advanced fluid devices.

Microfluidic System
In microscale, we could precisely manipulate liquid behavior, which is geometrically constrained to a small volume. We develop interesting and useful engineering applications in microfluidic system.
