I'm Zhendong Li, but I go by Justeen Lee. With a firm vision of harmonious integration of hardware and software, I strive to bring aha moments to people around me, by employing series of motion studies, arrays of sensor I/O's, and lines of code to hence define, visualize, and prototype interactions between humans, interfaces, devices and systems.
