Liquid-Crystal Technology
My work is organized around several interconnected research directions: liquid-crystal material engineering, reconfigurable optoelectronics, microwave and millimeter-wave devices, scalable printing and patterning technologies, flexible healthcare systems, and emerging reconfigurable photonic platforms. Together, these areas form a unified research vision: to build adaptive material systems that can sense, respond, and actively control electromagnetic energy across multiple length scales and frequency regimes.
Optoelectronics
I develop optical components that are electrically reconfigurable, ultra-thin, and versatile. My work includes smart windows with tunable transparency, polarization-dependent shutters, wide-viewing-angle displays, and devices that couple optical rotation with color modulation. These systems allow simultaneous control of intensity, color, and polarization of light, offering enormous potential in AR/VR, architectural optics, and information security. By combining optical physics with advanced LC chemistry, I pursue high-efficiency, multifunctional devices with minimal power footprint.
Microwave & mmWave
At high frequencies, I integrate liquid crystals into reflective and transmissive platforms such as bandpass filters, phase shifters, RIS, and phased-array systems. My research emphasizes performance metrics such as low insertion loss, fast tunability, angular beam control, and system scalability. These devices are designed to meet the demands of future 6G networks, satellite communications, and reconfigurable antenna arrays. Liquid crystal engineering enables devices that are lighter, more agile, and more customizable than conventional semiconductor-based counterparts.
Printing & Patterning Technology
I leverage drop-on-demand printing and laser-assisted patterning to build functional architectures from the micro- to millimeter-scale. These techniques drastically reduce material consumption, simplify fabrication workflows, and eliminate lithographic constraints. By enabling customized design of multilayer LC devices, this approach supports the development of soft, flexible, and wearable electronics. My research envisions a future where LC-based sensors, antennas, and optical elements can be seamlessly integrated into textiles, robotics, or deformable substrates—truly programmable matter through precision printing.
Antenna & Wireless Systems
My work now sits at the system level. At Samsung Electronics’ Advanced Antenna Lab, I work on antenna technologies for next-generation smartphones and emerging form-factor devices, where mmWave, UWB and satellite links have to coexist within tight constraints on space, materials and the rest of the device. This builds on system-oriented work from my research career: lightweight LC beamforming antennas in a defense R&D program, reconfigurable intelligent surfaces for 6G, and RF liquid-crystal materials developed for 5G and satellite communications. What interests me most is how choices at the material and device level carry through to link-level performance, and how advanced research can be brought to the point where it fits inside a real product.
Reconfigurable Photonics & Metasurfaces
I aim to extend liquid-crystal-based tunability into reconfigurable photonic and metasurface platforms, where light can be dynamically controlled through both structural and material-level degrees of freedom. By combining anisotropic LC media with photonic crystals, metasurfaces, and potentially MEMS-enabled architectures, I seek to engineer adaptive systems capable of controlling phase, resonance, polarization, chirality, and spectral response. This direction bridges my background in RF/mmWave wave control and optoelectronic LC devices with emerging nanophotonic platforms. The long-term goal is to develop hybrid reconfigurable photonic systems in which geometry, dielectric tensor, and external stimuli are co-designed to enable compact, programmable, and multifunctional optical hardware for sensing, imaging, communication, and next-generation display technologies.
