About me
I am a senior research scientist at NVIDIA Zürich where I work on fundamental machine learning theory and light-transport simulation. In salesmen terms: I do photorealistic rendering with artificial intelligence! :)
I did my doctorate at ETH Zürich and Disney Research where I had the pleasure to integrate some of my work into Disney's Hyperion Renderer. In my free time, I am most notably involved in developing the online rhythm game osu!, I also enjoy working on other kinds of software projects, and I like metalworking.

Selected Personal Projects
Real-Time Transient Rendering
WebGL brute-force path tracer for visualizing the propagation of light through space in slow motion. This toy project was inspired by femto photography and previous work on offline transient rendering by Jarabo et al. [2014] and Bitterli [2016].

tev — The EXR Viewer
A high dynamic range (HDR) image comparison tool for graphics people. tev allows viewing images through various tonemapping operators and inspecting the values of individual pixels. Often, it is important to find exact differences between pairs of images. For this purpose, tev allows rapidly switching between opened images and visualizing various error metrics (L1, L2, and relative versions thereof). To avoid clutter, opened images and their layers can be filtered by keywords.

osu!tp — Player Ranking System for the Online Rhythm Game osu!
Third party player ranking system based on automated analysis of gameplay patterns, which eventually became osu!'s official ranking system in an adapted form.
