Marc Droske

Applied Mathematician (Dr. rer. nat., PhD)

I'm Head of Rendering Research at Weta Digital, New Zealand.

Prior to joining Weta, I was a research mathematician at mental images which became NVIDIA Advanced Rendering Center, Berlin during the acquisition by NVIDIA, where I worked on GPU-accelerated path tracing (iray) and geometry processing algorithms.

I studied Applied Mathematics at the University of Bonn. I received my Diploma and PhD degree in the institute for Numerical Simulation (Bonn and Duisburg), where I wrote my dissertation

On Variational Problems and Gradient Flows in Image Processing (PDF) advised by Prof. Martin Rumpf.

In 2005-2006 I visted the math department at UCLA for a PostDoc with Andrea Bertozzi and Stanley Osher.
