About
Jun-Hee Na is a materials scientist and soft robotics researcher whose work sits at the intersection of stimuli-responsive materials, shape-programmable structures, and soft actuator systems. His research focuses on developing intelligent hydrogels and liquid crystalline materials capable of undergoing controlled mechanical deformation in response to external stimuli, including light, electric fields, and temperature. Na's most celebrated contribution is the development of "grayscale gel lithography," a elegantly simple yet powerful technique that programs non-Euclidean hydrogel plates to morph from flat sheets into precise three-dimensional shapes — work that has garnered 88 citations and holds significant implications for soft robotics, tunable optics, and bioengineering. Building on this foundation, he has pioneered electroactive hydrogel actuator systems capable of fast, flexible folding under low electric fields (78 citations), and advanced multipolar electric field modulation strategies to achieve complex freeform actuation beyond conventional bending motions. His investigations into thermally triggered bilayer hydrogels and, more recently, multiscale surface programming with liquid crystalline materials further demonstrate his breadth across functional material platforms. With over 200 cumulative citations, Na's research continues to shape next-generation approaches to programmable soft matter, making his work essential reading for students exploring smart materials and bioinspired robotics.
