Research Assistant
Aug. 2025 – Present · Urbana, IL, USA

Introduced a heterogeneous-visibility formulation for navigation under uncertain connectivity and developed a tree-based path-sampling algorithm with a utility-weighted observation reward; published at IROS 2026 [P2].

Industry Sponsored Research
Aug. 2025 – Dec. 2025 · Remote

Built a multi-agent chatbot that delivers transparent, source-grounded explanations of supply-chain optimization outputs for non-technical stakeholders.
Implemented an agentic RAG workflow in LangGraph with iterative retrieve–tool-use–validate loops; routed queries to role-based expert agents and synthesized answers via an aggregator.

AI Researcher
Feb. 2025 – Jul. 2025 · Seoul, South Korea

Proposed SIEVE, an SE(3)-equivariant self-supervised learning method for point clouds; scaled pre-training to 876k samples, resulting in a first-author NeurIPS 2026 paper [P1].
Developed and implemented SE(3)-equivariant deep learning models, including Transformer and Graph Neural Network architectures, using Python, PyTorch, and PyTorch Geometric.
Successfully trained equivariant models to predict Finite Element Analysis (FEA) simulations, achieving accuracy on par with standard baselines while guaranteeing SE(3)-equivariance.

Visiting Researcher
Jun. 2024 – Oct. 2024 · Montréal, QC, Canada

Designed a 2 degrees of freedom ankle joint using a compliant mechanism to enable inversion/eversion movements and dorsiflexion/plantarflexion.
Fabricated a 3D-printed prototype and integrated it with the existing PERL ankle exoskeleton to validate its mechanical performance.

Undergraduate Research Assistant
Sept. 2023 – June 2024 · Seoul, South Korea

Developed an automatic tuner for the parameters of the geometric tracking attitude controller for the quadrotor using the TD3 reinforcement learning algorithm.
Trained the reinforcement learning based tuner using data from a PyBullet quadrotor simulation wrapped in a Gym environment.

Undergraduate Research Intern
Mar. 2023 – Jun. 2024 · Seoul, South Korea

Derived a geometric trajectory-tracking controller for a collective pitch-tilting multirotor and established position, yaw, and pitch as differentially flat outputs.
Proved almost-global exponential attractiveness of the closed-loop dynamics using Lyapunov analysis and validated the controller in MATLAB.

English-Korean Interpreter/Translator
May 2020 – Feb. 2022 · Osan Air Base, South Korea

Enabled clear communication for Air Force Operations Command by accurately interpreting operational dialogues and translating technical documents for ROK and US Air Force leadership.
