About Me

Software engineer and Physicist


I earned my dual B.A. degrees in Data Science and Physics from UC Berkeley. I bring hands-on experience in building high-performance simulation tools, distributed computing frameworks, and scalable data pipelines. My technical foundation spans Python, C++, Java, and SQL, with a strong emphasis on machine learning, HPC, and end-to-end system design.

My project portfolio includes scalable word count systems using Ray, machine learning pipelines with PyTorch, and interactive web tools tailored for quantum research communities. I thrive in fast-paced, cross-disciplinary environments where clean architecture, data reliability, and impactful outcomes drive innovation.

UC Berkeley


I earned my dual B.A. degree in Physics and Data Science at the University of California, Berkeley, with a strong focus on computational modeling, simulation, and data engineering.


Throughout my undergraduate studies, I’ve worked across theoretical and experimental domains—bridging scientific research with real-world engineering applications. My experience spans quantum computing, particle physics, and systems development in both academic and national lab environments.

Ion Trap Engineering


My research in ion trap systems spans both theoretical and experimental work at UC Berkeley and Sungkyunkwan University.


At the Ion Trap Group under Professor Hartmut Häffner, I developed ML optimization models in PyTorch to extract optimal laser control parameters from noisy quantum hardware data, improving fidelity of frequency-modulated quantum gates. I also led the design of a thermal control system using laser heating and isolation techniques to achieve stable control of ion fluorescence at 500K, enabling robust and accurate initialization of quantum states in trapped-ion computers. This work was documented in both a research poster and a technical paper as part of the Berkeley Physics & Astronomy Undergraduate Research Scholars Program (BPURS).

In parallel, I collaborated with Professor Junki Kim at QuETI on developing a trapped-ion Hamiltonian simulator for a simplified spin-boson system. I built a Molmer-Sørensen gate simulator to track quantum state evolution and spin-motion entanglement over time—enabling more accurate modeling of gate-level interactions in ion-based quantum computers.

KATUSA


From 2020 to 2022, I served as a Sergeant in the Republic of Korea Army, assigned to the U.S. Army's 2nd Infantry Division as part of the KATUSA (Korean Augmentation to the United States Army) program.


During my service, I led a team of medics and KATUSA soldiers, developed secure communication pipelines between U.S. and ROK forces, and implemented a real-time health tracking system to monitor battalion readiness and improve emergency response times. I also had the honor to be the first KATUSA instructor for Combat Life Saver (CLS) certification, resulting in more than five ROK Army soldiers completing the program under my guidance.

For my service, I was honored with the Army Commendation Medal from the United States Army and the Army Warrior Award from the Republic of Korea Army. I also received two Certificates of Achievement from the U.S. Army in recognition of leadership and performance excellence.

Quantum Computing KR


I lead Quantum Computing KR, a Korean-language community dedicated to making quantum computing more accessible to students, researchers, and professionals.


Through this initiative, I created structured educational resources and documentation in Korean, covering topics from quantum algorithms to Qiskit tutorials. I also organized in-person seminars and online events featuring guest speakers from academia and industry, helping foster cross-institutional collaboration and technical learning within the community.

The group continues to serve as a hub for over 700 members and growing, offering peer support, collaborative learning, and a centralized hub for Korean-language quantum computing discussions.

I founded El Classic Berkeley, the Korean soccer club at UC Berkeley, in August 2022. What began as a casual community for Korean students has since grown into a well-organized team known for its spirit, inclusivity, and competitive play.


As team captain from 2022 to 2024, I led both on and off the field—coordinating matches, organizing training sessions, and managing club operations and recruitment. Under my leadership, the team grew in size and recognition, building a tight-knit community for Korean students through weekly practices, tournaments, and social events.
