Applied Scientist - Computer Vision

Computer vision systems for real-world data.

I build applied vision models for object detection, segmentation, 3D perception, low-light imagery, point clouds, and efficient deployment.

Detection, segmentation and 3D perception

My work focuses on robust models that handle noisy data, domain shift and limited labels.
