Research Interests
In the Koh Lab, three different systems take advantage of our unique expertise in material composite interfaces. 1) Polymer composites of room temperature liquid metal are formulated and characterized for applications in soft robotics and stretchable electronics. 2) Novel coatings and actuation methods are developed in magnetorheological fluids for prosthetics and earthquake dampers. 3) High internal phase emulsion polymer foams are functionalized to target high impact pollutant and contaminant systems with a variety of flow environments.
