Introduction
I am an Assistant Professor in the Computer Graphics and Visualization Group at TU Delft. I conduct research in computational imaging and displays covering both perceptual aspects of AR/VR/lightfield displays as well as computer vision techniques for 3D scene representation including neural rendering.
Since 2019, I have been a Visiting Scholar in the Stanford Computational Imaging Lab of Prof. Gordon Wetzstein at Stanford University and Senior Technical Staff member at Raxium.
Between 2017 and 2019 I was a Postdoctoral Associate in the Computational Fabrication Group of Prof. Wojciech Matusik at MIT CSAIL.
Between September 2012 and December 2016 I was a PhD Student in the Computer Graphics Department at MPI Informatik and Saarland University under supervision of Prof. Karol Myszkowski and Prof. Hans-Peter Seidel.
I have defended my PhD thesis Perceptual modeling on stereoscopic 3D on 4th November 2016 and obtained degree Dr.-Ing. with summa cum laude.
Research Interests
- Computational displays and perceptual rendering
- Neural rendering and 3D GANs
- Computational imaging and deep learning
- Appearance based gaze tracking
- Neural sensing
Open Positions
I am looking for enthusiastic Master students interested in development and evaluation of perception-driven algorithms for capture, processing and rendering of light fields for advanced display applications including virtual and augmented reality. The topics include among others neural rendering, generative image synthesis, perceptual modeling and display algorithms.
