Falk Wiegmann

Ford Lab, UBC · Vancouver, BC

Hi! I’m a PhD student in the Ford Lab at the University of British Columbia, where I work on image reconstruction for preclinical cone-beam micro-CT. My research sits at the intersection of imaging physics and machine learning. I study the resolution and noise limits of cone-beam reconstruction, and I build learning-based methods (projection infilling and implicit neural representations) that aim to improve image quality.

Outside of research, I like to surf, work on my boat, ski and golf.
