Ahmed Kedir Mohammed

About

I am a Research Scientist at SINTEF Digital and an Adjunct Associate Professor at NTNU. My research is broadly focused on machine learning and computer vision, with an emphasis on 3D vision and medical imaging for explainable and data-efficient learning. My current work involves deep learning for point cloud processing, underwater navigation, and capsule video endoscopy.

With a background in both academia and industry, I have experience leading AI projects in areas like autonomous systems and multimodal learning. My goal is to translate research into real-world applications
