Inverse problems for various imaging modalities:
- natural image restorations (super-resolution, denoising, deblurring, etc.)
- medical image reconstructions (MRI, CT, SIM, Cryo-EM, DOT, EEG, fMRI, etc.)
Bridging between signal processing and deep learning communities:
- providing a design principle for deep learning architectures
- network analysis using topological data analysis (TDA)
Deep generative models:
- developing a high fidelity and diverse image-to-image translation model
- improving generative models based on theoretical understandings

In a broad sense, my research direction is to develop novel learning algorithms which overcome remaining challenges of deep-learning techniques.

The current deep learning algorithms are
i) dependent on a massive amount of training data,
ii) hard to generalize to unseen tasks and iii) difficult to learn a new concept on the learned knowledge.

To tackle these problems, I`m interested in following topics:
- few-shot learning, meta-learning, lifelong learning (continual and incremental learning)
- meta-reinforcement Learning and causal learning.

Surface-enhanced Infrared Absorption Spectroscopy
We are developing a novel class of plasmonic structures for Surface-enhanced infrared absorption (SEIRA) spectroscopy. Extremely high near-field enhancement and enhanced sensing area formed at various plasmonic metamaterial structures may provide a promising sensing platform for future applications of ultrasensitive biological and chemical sensing and detection.
Active metasurfaces
We are developing ultra-fast electrically-tunable plasmonic metasurfaces based on coupling of plasmonic resonances in metallic nanostructures with intersubband transitions in multiple-quantum-well (MQW) structures.
Nonlinear metasurfaces
We are developing highly-nonlinear metasurfaces based on coupling of electromagnetically-engineered plasmonic nanoresonators with quantum-engineered intersubband nonlinearities.
