# About me

I am a post-doc in the topology group of Prof. Dr. Arthur Bartels. I did my PhD thesis under supervision of Prof. Dr. Thomas Schick in Göttingen. My research interests are connections between operator algebras and algebraic topology, in particular (twisted) K-theory and index theory. Since I studied theoretical physics before my PhD, I am also interested in topological and conformal field theories with a view towards elliptic cohomology.

# Recent activities

- During the winter semester 2013/2014 I am organizing the exercise session of the Introduction to Algebra and I am organizing a seminar about Manifolds and Homotopy Theory (i.e. cobordism theory) together with Johannes Ebert.
- I gave a talk about recent work at the conference Twists, generalised cohomology and applications that took place in Münster from October 14th to 18th 2013.
- I gave two talks at the meeting of the String Geometry Research Network at the MPI in Bonn. The first one about Spin groups and spin representations was part of a reading course. The second was about my recent work on Unit spectra of K-theory via strongly self-absorbing C*-algebras.
- From September 29th to 27th 2013 I visited Christian Ausoni at Universite Paris 13 and I gave a talk in the seminar of the topology group.
- From September 25th to October 04th 2013 I visited Branislav Jurco at the University of Prague to discuss a joint project.
- From September 14th to 20th 2013, I visited Marius Dadarlat at Purdue to discuss our joint work. I gave a talk about its status in the operator algebra seminar.
- On September 11th 2013, I gave two talks in the seminar of the topology group at the University of Berkeley. An introductory one about K-theory of C*-algebras and another one about my recent work.
- I am a member of the String Geometry Research Network. Our next meeting will be from October, 7th to October 11th 2013 in Bonn.
- I am organizing the exercise session for the lecture Algebraische Topologie 2 by Johannes Ebert during the summer semester 2013.
- I am organizing a seminar about Topological Methods in Group Theory together with Johannes Ebert during the summer semester 2013
- I gave a lecture about topological quantum field theories during the winter semester 2011/2012.
- I will attend the Workshop "The structure and classification of nuclear C*-algebras" from April, 15th to 19th at the ICMS, where I will speak about recent results worked out in collaboration with Marius Dadarlat
- I will attend the NCGOA 2013 from May, 3rd to 9th
