[Laboratory Introduction and Brief Biography]

Rho's research group is not only developing a new concept of novel optical nanomaterials having extraordinary and unprecedented eletromagnetic properties based on fundamental physics and experimental studies of deep sub-wavelength light-matter interaction, but also realizing engineering device applications including, but not limited to, super-resolution imaging, negative index materials, tunable high refractive index metasurface, highly efficient light trapping device, ultra-sensitive biomedical sensor, nanoscale laser, and next generation scalable nanomanufacturing methodologies.

Prof. Rho is an Associate Professor who joined Pohang University of Science and Technology (POSTECH), with a double appointment in the Department of Chemical Engineering and the Department of Mechanical Engineering. He received his Ph.D. degree in Mechanical Engineering with designated emphasis in Nanoscale Science and Engineering at the University of California, Berkeley (2013), M.S. degree in Mechanical Science and Engineering at the University of Illinois, Urbana-Champaign (2008) and B.S. degree in Mechanical and Aerospace Engineering at Seoul National University, Korea (2007). Prior joining POSTECH, he conducted postdoctoral research in Materials Sciences Division & Molecular Foundry at Lawrence Berkeley National Laboratory. He also worked as a principal investigator (Ugo Fano Fellow) in Nanoscience and Technology Division & the Center for Nanoscale Materials at Argonne National Laboratory. 

Prof. Rho has authored and co-authored more than 70 high-impact journal papers including Science, Nature, Nature Materials, Nature Photonics and Nature Communications. He is also the recipients of several notable honors and awards such as MRS graduate student award (2011), SPIE scholarships in optics and photonics (2011,2012), OSA Incubic/Milton Chang Award (2013), Samsung Lee Kun-Hee fellowship (2008-2013), DOE Argonne Named fellowship (2014), Edmund Optics Award (2015), OSK Young Investigator Award (2016), SPIE Rising Researcher Award (2017), Korean Ministry of Science, ICT and Future Planning Minister's Commendation (2017).
