Power management IC designer, chip photographer, and occasional artist.

I design power management circuits for modern SoC platforms and emerging AI hardware systems — computational digital LDOs, SIMO DC–DC converters, switched-capacitor converters, and voltage-stacked power delivery for high-bandwidth memory systems. Advised by Prof. Mingoo Seok at Columbia University. Beyond the lab, this site also collects the chips I've taped out and a few frames from my camera.
