Reading structure into unstructured data

My work sits at the intersection of 3D geometry and learned perception — teaching models to find reliable structure in noisy spatial data. That has meant separating tree crowns from depth maps over an orchard, tracing feature lines across a 3D-scanned heritage site, and training a transformer-based segmentation model to parse multimodal scans of horses for a research dataset.

I'm currently completing an MSc in Artificial Intelligence at the University of Cape Town and looking to continue this line of work at the PhD level — with particular interest in transformer-based 3D segmentation, multimodal registration, and applied computer vision for scientific and cultural-preservation use cases.
