Dr. Lukas F. Lang

Researcher

Biography

I am a researcher in applied mathematics and computational science. Currently, I am an external lecturer at the Faculty of Informatics at TU Wien.

Until recently, I held a position as a research associate within the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge. I was a member of the Cambridge Image Analysis group and was supervised by Carola-Bibiane Schönlieb.

Prior to Cambridge, I was a research scientist at the Johann Radon Institute for Computational and Applied Mathematics (RICAM) and part of the Inverse Problems and Mathematical Imaging group.

I earned a PhD in Computer Science from the University of Vienna, where I was supervised by Otmar Scherzer. During my PhD studies I was a member of the Computational Science Center (CSC) and of the Vienna Graduate School in Computational Science.
