Research Interests

Circuit & Hardware Systems: Specialized in Analog Circuit Design and DAC architectures utilizing Cadence-OrCAD and Verilog for high-performance modeling.
Software & Network Systems: Expertise in Computer Networking and Security using C, Rust, and Python for high-performance systems, alongside Java and Scala.

Research Experience

8-bit 100MS/s full-binary Current Steering DAC

KAIST, Mixed Signal Integrated Circuits Lab. | Prof. Ryu, Seung-Tak | 2023.06 ~ 2023.08

Studied factors impacting nonlinearity of Current-Steering DAC and mitigation techniques.
Designed Current Cell and Switch Driver on TSMC-180nm in OrCAD; validated via testbench (60dB SFDR at Nyquist).
Improved performance by adjusting CMOS conditions for 2Gs/s clock operation (58.3dB SFDR at Nyquist).

Analysis of DETR Model and Comparative Study of Backbone Performance

KAIST, Video and Image Computing Lab. | Prof. Kim, Mun-churl | 2025.06 ~ 2025.08

Reviewed YOLO, Transformer, DETR, Swin Transformer to analyze object detection evolution.
Built deep learning environment; compared Swin Transformer vs ResNet-50 backbones to address DETR convergence.
Found ResNet-50 superior in speed/stability/generalization; Swin’s local attention hurt DETR’s global context modeling.

Work Experience

Internship Program

Hankook Tire & Technology | Digital Intelligence Team | 2025.09 ~ 2026.02

Big Data Infrastructure & Standardization: Built “HKT Equipment Data Standardization Process” for ~1Trillion (4TB) PLC-IoT raw data.
Advanced Data Modeling: Designed diffusion-based upsampling to overcome 1s sampling limits, enabling precise cycle/spec classification.
AI-driven Anomaly Detection: Developed LSTM/CNN/AE models on preprocessed sensor data to enhance defect detection.
System Development: Implemented permission-level management for secure remote equipment monitoring/operations.
