Biosketch

  • Dr. Yeongjun Lee is a materials scientist who studies brain-computer interfaces based on soft electronic materials. He is currently working as an assistant professor in the Department of Brain and Cognitive Sciences at KAIST.
  • After obtaining his bachelor's degree in the Department of Materials Science and Engineering (MSE) at Hanyang University, he completed his master's/doctorate in MSE at Pohang University of Science and Technology and worked as a postdoctoral researcher in MSE at Seoul National University (Advisor: Prof. Tae-Woo Lee). During this period, he studied flexible/stretchable biocompatible soft electronic materials, various semiconductor devices, and neuromorphic electronic devices.
  • Afterwards, as a staff researcher at the Materials Research Center of the Samsung Advanced Institute of Technology, he studied stretchable materials and bioelectronic devices for next-generation wearable digital healthcare devices. Then as a postdoctoral researcher at Stanford University, he worked with Prof. Zhenan Bao on high-resolution soft neural electrodes and low-power neuromorphic prosthetics.
  • Dr. Lee's Soft NeuroElectronics Lab studies high-density soft neural electrodes, neuromorphic electronic devices, and flexible/stretchable bioelectronic devices based on polymer electronic materials that are highly biocompatible with biological tissues. It researches functional materials and high-performance devices that can seamlessly integrate with the body and tissues, and apply them to animal models with neurological diseases. The lab aims to improve our understanding of the brain and nervous system and develop next-generation neural interfaces and low-power neuroprosthetic systems that can be used in the diagnosis and rehabilitation of neurological disorders. Through this, the goal is to contribute to improving the quality of life of patients with neurological diseases.
