Hongki Kang, PhD

an Electrical Engineer in Microelectronics for novel bio-electronics and biomedical engineering applications

From February 2019, I am joining the Department of Information and Communication Engineering (ICE) at DGIST (Daegu Gyeongbuk Institute of Science & Technology) in South Korea as an Assistant Professor. I will be mostly working on Bioelectronics & Neural Engineering (Brain-Microelectronics Interface, Neuromodulation) areas of research using microelectronics, microfabrication processes, and new bio-functional materials.


I will be looking for students who would like to do research at the intersection of microelectronics & biomedical engineering. If interested, please send me an email.

마이크로 전자 (트랜지스터, 센서, 회로)와 미세 공정 (나노 물질 공정, 프린팅 등)을 이용하여 바이오 전자 분야 (바이오 공학, 뇌공학, 헬스케어, 생체 신호 습득 및 조절)에 응용하는 연구에 관심을 가지고 새로운 출발을 함께 하고 싶으신 학생들, 연구원 분들의 관심 바랍니다.

Starting my research career in semiconductor devices in EE, I have been expanding my expertise towards neural engineering. I earned my PhD in Electrical Engineering at University of California, Berkeley in 2013, under the supervision of Vivek Subramanian. After PhD, I spend a year at Columbia University as a postdoctoral research scientist in Dr. Kenneth Shepard's lab. Since then, I have been working as a postdoctoral researcher in Neural Engineering Lab (PI: Prof. Yoonkey Nam) in the Department of Bio and Brain Engineering & Information & Electronics Research Institute at KAIST (Daejeon, South Korea) until Feb. 2019.


I am an electrical engineer specialized in both Electrical Engineering and Biomedical Engineering applications. In particular, during my PhD, I have worked on large-area, low-cost, flexible, printed electronics processes and devices that can build electronics in new form factors (e.g., flexible, wearable). My general research interest includes improvement in our healthcare technology by developing new concepts of devices, fabrication processes, and understanding fundamental science governing those applications.

For the last few years as a postdoc, I have been working in the area of neural engineering:

    • how novel transistors/ICs record physiological signals;
    • how to leverage novel fabrication processes / electronic devices (novel IC etc.) to interface with physiological signals better;
    • how printing bio-functional nanoparticles can advance bioengineering applications (e.g., thermo-plasmonics for neuro-modulation).
