Passionate Researcher in AI & Medical Imaging

Exploring the frontiers of Computer Vision, Medical Imaging, and AI Agents to solve real-world healthcare challenges.

Hi, I'm Moein! 👋 A passionate researcher pushing the boundaries of AI in healthcare.

I'm a PhD student in Biomedical Engineering at the University of British Columbia, working under the supervision of Dr. Ilker Hacihaliloglu at the UltrAi Lab.

My research explores the frontiers of Computer Vision, Medical Imaging, and Deep Learning. I'm particularly interested in Implicit Neural Representations, Vision Transformers, Diffusion Models, AI Agents, and Large Language Models for medical applications.

Currently, I'm developing an agentic framework for echocardiography, combining multimodal AI agents with advanced vision models to improve cardiac imaging analysis and diagnosis.

I've had the privilege of collaborating with leading researchers from Stanford, RWTH Aachen, MILA, MBZUAI, and Rutgers, publishing at top-tier venues including CVPR, ICCV, MICCAI, WACV, and Medical Image Analysis.
