About me

I'm a Ph.D. student working in the Visual Computing group at the University of Konstanz. My area of research is information visualization, with a focus on visualization of uncertainty. I'm curious to work on challenging problems and understand their theoretical and mathematical foundations. Lately I have been working on visualizations that help us understand machine learning algorithms.

Misc

When I'm not spending time with my family or working, you often find me with friends in the mountains going backcountry skiing or climbing. I also enjoy traveling and exploring new places. Below are some photos that I took along the way.
