## Connecting Algebraic Geometry and Applied Topology

The main reason for doing a postdoc at the Max-Planck Institute was to learn more algebraic geometry and to deepen the connections between the applied topology and applied algebraic geometry communities. The following paper is the first result in that direction.

- "Learning Algebraic Varieties from Samples" (joint work with Bernd Sturmfels, Paul Breiding and Madeleine Weinstein). In
*Revista Matemática Complutense*, Volume 31, pages 545–593, 2018. - "Finding the Homology of Manifolds using Ellipsoids" (joint work with Davorin Lesnik). Supplementary programs are available here: AngleBetweenProjectionAndHalfline.nb, ProjectionNotOnHalfline.nb, ellipsoids.cpp. Accepted for publication in
*Journal of Applied and Computational Topology*.

## Parametrized Homology, Alexander Duality and Applications to Sensor Networks

- "Parametrized Homology via zigzag persistence" (joint work with Gunnar Carlsson, Vin de Silva and Dmitriy Morozov). In
*Algebraic and Geometric Topology*. - "Alexander Duality for Parametrized Homology". In
