Biography

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 Emory’s Scientific Computing Group. I lead the Emory REU/RET site for Computational Mathematics for Data Science. 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 by grants from the US Israeli Binational Science Foundation, the US Department of Energy’s Advanced Scientific Computing Research program, the Air Force Office of Scientific Research, and contracts by Sandia National Laboratories. Previously, I was supported by the Centers for Disease Control.

Research

My research and teaching sit at 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. I also develop machine learning approaches for solving high-dimensional partial differential equations and optimal control problems and am interested in connections to active and reinforcement learning.

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.
