Research：Smart soft matter, living matter, 3D 4D printing, nanomanufacturing, biomimetics, micro nanooptics

Qi-Huo xk星空官网 graduated from Department of Physics, Nanjing University in 1993 with a PhD in condensed matter physics. Prior to joining SUSTech, he was a tenured professor at the Liquid Crystal Institute and Department of Physics in Kent State University in US. He was a recipient of Alexander von Humboldt research fellow and the CAREER award of National Science Foundation. Prof. xk星空官网 has a broad research interest, covering statistics physics, optics, mechanics, material engineering, sensors, and biomimetics, and has made original contributions in single file diffusion, nanoparticle plasmonic coupling, Brownian motion of low symmetry particles, command of living matter, and photoalignment. He proposed the concept of plasmonic metamasks and invented a photopatterning technique allowing for photopatterning arbitrary designer molecular orientations in single exposure, just like photolithography. This technique is important for liquid crystal polymer flexible substrates, reconfigurable metamaterials, optoelectronic devices, liquid crystal elastomers and biomedical applications. His research has been supported by National Science Foundation, Department of Energy and Samsung Electronics.
