Minjun Lee is a PhD candidate in Bioelectronics at POSTECH, supervised by Prof. Steve Park. His thesis develops thin-film organic electrochemical transistor arrays on flexible polyimide substrates for chronic subdural neural signal recording in freely moving rodents, demonstrating signal-to-noise ratios exceeding standard platinum electrode arrays across twelve weeks of implantation. Ten publications in Advanced Materials, ACS Nano and Small document his device fabrication and in vivo electrophysiology results. Minjun received a Samsung Future Technology initiative grant and completed a collaborative project with the Wyss Institute at Harvard on bioresorbable electronics. He has accepted a senior engineer role at Neuralink to develop next-generation flexible electrode arrays for human clinical trials. His OECT arrays resolve single-unit spikes from 256 channels simultaneously at 30 kHz sampling rate.
