Welcome! My name is Jens Reinhold and I am a mathematician. I hold a PhD from Stanford University, where I wrote my thesis under the guidance of Søren Galatius.

I am interested in algebraic and geometric topology, especially in moduli spaces, fiber bundles, and applications of homotopy theory to geometry, with a special focus on the topology of manifolds.

To contact me, send an email to where you replace x and y by my given name and family name, respectively.
