New York University Abu Dhabi

• B.S. Computer Engineering (May 2028)

Work Experience

🛰️ Undergraduate Researcher @ Spacecraft Prototyping Laboratory (SPL), KAIST (June 2026 - August 2026)

Free-Space Optical Communication, Closed-Loop Pointing Control, Link Characterization

• Tested closed-loop control of a fast steering mirror (FSM) for fine beam pointing on the lab’s free-space optical (FSO) communication testbed
• Characterized FSO link quality through bench-top SNR measurements on lab hardware and BER performance analysis — see fso-baseline-snr
• Building attitude-determination foundations — quaternion kinematics and multi-sensor attitude estimation — toward the lab’s star tracker and satellite GNC research

🧑‍🎓 Summer Research Assistant @ Engineering Design Studio (May 2023 - July 2023)

• Collaborated with NASA-JPL engineers from Group 355A (Architecture and Formulation Group) to design and deliver a flight-ready Hold-Down-and-Release Mechanism (HDRM)
• Developed embedded flight-control firmware for staged event triggering and actuator command sequencing on an experimental sounding rocket, flight-tested at Spaceport America Cup 2023
• Engineered custom PCBs (power distribution and flight controller) and the corresponding embedded systems

Projects

📡 Optical Ground Station (OGS) Live Link Budget Simulator (2026)

FSO Channel Modeling, Pointing-Jitter Statistics, MATLAB GUI

• Built an interactive MATLAB simulator evaluating link margin and tracking reliability of satellite-ground laser links
• Integrated a live weather API to scale atmospheric attenuation from real-time humidity, cloud cover, and precipitation
• Modeled fine-pointing error as Rayleigh/Rician-distributed jitter to compute time-series link margin, margin probability density, and link outage rate; Configured to SPL’s optical ground station at KAIST.

🎻 StringSense — AI Practice-Coaching Pickup (June 2026 - Present)

Analog Front-End Design, Embedded Firmware, PCB Design/Fabrication, Mechanical CAD — Solo Founder @ KAIST OVERGE Program

• Independently designed a real-time wireless sensing device for bowed string instruments: dual-piezo analog front-end (op-amp buffering, anti-alias filtering), multi-channel ADC acquisition on an nRF52840, and BLE streaming to a phone
• Owned the full sensing chain — sampling and anti-aliasing strategy, low-power wake logic via on-chip analog comparator (LPCOMP), KiCad PCB layout carried through fabrication, and enclosure CAD

🚀 HaloShip (Spaceport America Cup 2023) (Sep 2022 - June 2023)

Embedded Flight Control, Sensor Fusion, Avionics, CAD, Stress/Aero Simulations — title links to launch footage 🎥

• Led design of a reusable experimental sounding rocket with modular subassemblies for complete assembly/disassembly
• Implemented a dual-redundant, non-pyrotechnic parachute deployment system with multi-sensor-fusion triggering logic for fail-safe recovery event timing
• Developed custom avionics including a flight computer for real-time sensor data acquisition and a high-speed data acquisition payload

⚙️ NASA-JPL University Crowdsourcing Initiative (JUCI) (Sep 2022 - June 2023)

Actuation Mechanism Design, CAD, Stress Simulations

• Delivered a solenoid/actuator-triggered Hold-Down-and-Release Mechanism (HDRM) for CubeSats and small space missions
• Reduced system costs by 90% (approximately $10,000 > $1,000) while maintaining NASA flight requirements
