Topology
Ich interessiere mich für Topology vom Standpunkt der Homotopietheorie aus, also das Studium von geometrischen Objekten bis auf stetige Deformation.Die Homotopietheorie ist eng verwand mit der Höheren Kategorientheorie (insbesondere unendlich-Kategorien). Eines der Hauptgebiete in denen ich in den letzten Jahren gearbeitet habe ist die höhere Algebra, also das Studium von Ringspektren und Spektren mittels algebraischer und arithmetischer Techniken.
