Research

Research Interests

Representation Learning

Representation Learning

Learning compact, structured embeddings from high-dimensional data. Focuses on contrastive and self-supervised methods, data embedding, and latent space geometry.

Deep Learning on Time Series

Deep Learning on Time Series

Temporal and spatio-temporal modeling for forecasting and classification of multivariate sensor streams. Covers sequence models, graph-based dependencies, and large-scale time-series architectures.

AI for Science

AI for Science

Applying deep learning to physical and biological signals — IMU, EEG, and multivariate sensor data. Integrates physics priors, domain constraints, and signal structure into model design.
