Research experience

Three studies, one question: what does cross-session EEG actually carry?

Phenotype-Aware Personalization for Cross-Session EEG Emotion Recognition

2025 to 2026
  • Investigated cross-session performance degradation in EEG-based emotion recognition by analyzing the SEED-IV dataset across three weekly recording sessions per participant.
  • Implemented variance decomposition and two-way ANOVA to partition performance variance, examining whether cross-session variability reflects structured individual differences rather than random noise.
  • Conducted brain-behavior correlation analysis and hierarchical clustering to identify distinct user phenotypes affecting cross-session model generalization.
  • Developed and evaluated personalized fine-tuning strategies, demonstrating the efficacy of phenotype-aware domain adaptation over uniform correction methods for cross-session reliability.

EEG-Based Frequency Band Analysis for Cognitive State and Biometric Applications

2025
  • Independently analyzed a publicly available EEG dataset of 20 participants across three weekly recording sessions to investigate frequency band dissociation between task classification and person authentication.
  • Implemented a complete preprocessing pipeline with ICA artifact removal and computed cognitive engagement metrics including Theta-to-Alpha Ratio and Engagement Index.
  • Developed and evaluated EEGNet with Squeeze-and-Excitation blocks, Channel Mixing variants, and EEGPT architectures for cognitive state classification across seven frequency bands.
  • Conducted cross-session subject authentication experiments, discovering that delta oscillations achieved 86.9% task classification accuracy but only 15.6 to 23.6% authentication accuracy, while broadband signals reached 69.9% authentication performance.

Cognitive Load Analysis in Virtual Reality and Traditional Display Environments

2024 to 2025
  • Designed an experimental protocol comparing cognitive load during 360° VR immersive viewing versus 2D laptop display with 30 participants using a 14-channel Emotiv EPOC X.
  • Developed a preprocessing pipeline incorporating bandpass filtering, ICA artifact rejection, and signal normalization, then extracted Theta-Alpha Ratio, Engagement Index, and Beta-Alpha Ratio.
  • Performed statistical validation using MANOVA and ANOVA with FDR correction and built classification models with SVM, Random Forest, and kNN using five-fold cross validation.
  • Demonstrated that VR environments reduced cognitive load by 21% while increasing engagement by 59%, achieving 83.5% classification accuracy with TAR identified as the optimal marker.
