About Me
Hi! My name is Han, and I'm a Senior studying Aerospace and Electrical Engineering at Illinois Tech.
During my time at IIT, I lead the R&D team to develop solid & liquid propulsion systems, custom flight computers, GPS systems and launch high altitude dual-stages rocket. My goal is to work on solid propellant and composite manufacturing for sounding rockets.
Thus far, I have focused my engineering efforts in the following areas: rocket launch engineering and production; propulsion development, design, and testing; composite material; rocket software and hardware; and unmanned aerial vehicles.
When not working, I spend my free time taking photo, watching documentaries, drawing, baking, and playing the piano.
