Research Interests

I am interested in RGB-D data processing for 3D reconstruction using variational methods, especially photometric approaches and super-resolution.

Brief Bio

I received my B.Sc. in Mathematics from the OTH Regensburg in 2013 and my M.Sc. in Mathematics in Science and Engineering from the Technical University of Munich in 2016. Since mid November 2016, I am a PhD student in the Computer Vision Group, headed by Prof. Dr. Daniel Cremers at TUM. In May 2019 I was a visiting Ph.D. student at the GREYC Image Group, Caen, France under supervision of Yvain Quéau. From September 2019 until February 2020 I was interning as Research Intern at Facebook Reality Labs in Cork, Ireland under supervision of Thomas Whelan. From July 2020 onwards I'll be working part-time at Pro Unlimited @ Facebook as an External Research Collaborator to continue the project of my internship at Facebook Reality Labs.
