Professional Experiences

1. Powertrain Optimization Research Intern, KAIST

Sep 2023 - Aug 2024

R&D, Product Development, Engine Simulation (GT-Suite), Testing & Validation

Performed high-altitude performance simulations of a Hyundai CI diesel engine with a two-stage turbocharging system, evaluating compressor and turbine behaviour under reduced atmospheric pressure.
Calibrated a 1D GT-Power engine simulation model using real engine data, achieving less than 6% deviation.
Analyzed low-pressure turbocharger boost control strategies to enhance power delivery, thermal efficiency, and fuel consumption while meeting emissions standards.
Delivered validated design recommendations and supporting technical documentation to industry partners.
Demonstrated the feasibility of reciprocating engines for aviation applications through simulation and validation, achieving only a 10% power reduction at the target altitude compared to sea-level performance.

2. Battery Research Intern

May 2022 - Aug 2022

R&D, Data Analysis & Post-processing , Life Cycle Assessment (LCA), Experimental Testing (Chassis-dynamo), MATLAB

Performed road, chassis dynamometer and environmental chamber testing on a lithium-ion battery for an electric scooter to assess thermal durability and performance.
Installed and configured sensor-based data logging systems for capturing voltage, temperature, and current during load cycles.
Processed test results in MATLAB to evaluate energy efficiency and calculate well-to-wheel CO₂ emissions.
