Lars Ruthotto

Associate Professor of Mathematics and Computer Science

Emory University, Atlanta, GA, USA


I am an applied mathematician developing computational methods for machine learning and inverse problems. I am an Associate Professor in the Department of Mathematics and the Department of Computer Science at Emory University and a member of the Scientific Computing Group. Prior to joining Emory, I was a postdoc at the University of British Columbia and I held PhD positions at the University of Lübeck and the University of Münster.

I received an NSF CAREER award and am also supported grants from the US Israeli Binational Science Foundation, the US Department of Energy’s Advanced Scientific Computing Research program, and the Air Force Office of Scientific Research. Previously, I was supported by the Centers for Disease Control.

My research and teaching focus on the intersection of applied mathematics and data science, particularly deep learning and inverse problems.

In deep learning, I seek to create new insights and efficient training for continuous models based on ordinary and partial differential equations. Also, I develop machine learning approaches for solving high-dimensional partial differential equations and optimal control problems.

In inverse problems, I have been focusing on applications in image registration and reconstruction and computational techniques including optimal experimental design, uncertainty quantification, numerical optimization, multiscale and multigrid methods, and regularization. Over the years, I had many fruitful collaborations with domain-experts from public health, geophysics, and medical imaging.
