# Jakob Hansen

I am an applied mathematician focusing on using tools from algebraic topology and spectral graph theory to understand and design networks and systems. I graduated from the University of Pennsylvania in May 2020 with a PhD in Applied Mathematics and Computational Science, under the direction of Robert Ghrist. Beginning in August 2020 I will be a Visiting Assistant Professor in the Department of Mathematics at Ohio State University, as part of the Topological and Geometric Data Analysis group.
