Overview

Our research sits at the intersection of applied mathematics, signal processing, and deep learning, with a focus on developing computational methods that push the boundaries of medical imaging quality and accessibility. We work on inverse problems where the goal is to recover high-fidelity images from limited, noisy, or otherwise degraded measurements.

A core theme across our work is making advanced imaging more practical: reducing the data and hardware requirements, improving reconstruction speed, and enabling new clinical applications in medical imaging with a focus on ultrasound, photoacoustic, and cardiovascular imaging.

Research Themes

Photoacoustic Imaging

Developing deep learning-based reconstruction methods for photoacoustic tomography under limited-data and noisy conditions. Work includes sinogram super-resolution, dimensionality reduction with plug-and-play priors, denoising diffusion models, and image quality assessment.

Image Reconstruction Super-Resolution Diffusion Models

Ultrasound & Cardiac Imaging

Deep learning for echocardiographic image analysis including left ventricle segmentation (LVNet), bandwidth enhancement, beamforming, and automated segmentation of aortic aneurysms in 3D time-resolved ultrasound.

Segmentation Echocardiography 3D Ultrasound

Medical Image Segmentation

Designing efficient deep learning architectures for multi-organ and multi-modal segmentation, including brain tumor segmentation (MTAU), breast ultrasound, and cardiac structure delineation using transformers.

U-Net Transformers Multi-modal

Federated & Privacy-Aware Learning

Investigating robustness and security of federated learning in medical settings, including minimal data poisoning attacks on distributed medical image classification systems.

Federated Learning Adversarial Robustness Security

Cardiovascular Signal Processing

Deep learning methods for ECG classification, cardiac rhythm analysis, respiratory distress quantification, and smartphone-based estimation of physiological parameters for remote monitoring.

ECG Analysis Remote Monitoring 1D-CNN

Computational Pathology

Image-guided filtering for histopathology microscopy, whole slide imaging augmented by computational methods, and tumor cellularity assessment in breast cancer histology images.
