Research
Recovered geometry didn't beat photographs at finding scratches, but it kept working when the material changed.
Inverse Rendering for Industry Inspections: Are surface scratches easier to find in SVBRDF maps recovered by inverse rendering than in the photographs themselves?
results
407scratches, all found from near-field image input, which beat even ground-truth normal maps
≈50%higher score for normal maps when only the material's appearance changes

I'm finishing an MSc in Media Technology and Engineering at Linköping University, with the focus pulled hard toward computer graphics, GPU programming, and applied machine learning. My thesis, hosted at SICK IVP, is done. One 6 HP course stands between me and the degree, so November 2026.
I came at graphics through art: years of figure and gesture studies, until code turned out to be a way to build worlds the way drawing built faces and figures. Most of what I build lives on the line between graphics and systems: GPU-driven voxel engines, fragment-shader path tracers and, lately, a volumetric cloud renderer.
The next things are further down the stack: a physics engine in C++, Vulkan after a few years of OpenGL, and .NET. I'm looking for strong engineering work in systems, graphics, vision, or simulation.
