Welcome to the Kim Research Group @ POSTECH

Our research focuses on fundamental and applied investigations of soft matters (emphasis on liquid crystals).  We seek to understand intermolecular / interparticle / interfacial phenomena in soft materials to provide insights into the design of new class of responsive materials (smart materials) that will find applications in a variety of field, including Drug delivery/release, Sensors, Actuator (Micro-machine), Microfluidics, and Molecular/colloidal self-assembly.

If you are interested in joining our lab, please feel free to contact Prof. Young-Ki Kim

본 연구실에서는 첨단 연성물질 개발 및 특성 분석을 연구할 대학원생 및 박사후 연구원을 모집하고 있습니다.
관심 있는 학생 및 연구원은 주저 마시고 언제든지 연락 주시기 바랍니다.
