# String Geometry Network - Meeting, 18. - 22. Aug

# 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 2014/2015 I am organizing a seminar about Positive scalar curvature metrics together with Johannes Ebert.
- From October 6th to 9th I will be participating in the conference Methods of Noncommutative Geometry in Analysis and Topology in Hannover
- During September I will participate in the trimester on Noncommutative Geometry and its Applications at the HIM in Bonn
- From August 25th to August 29nd I will be visiting Glasgow for a masterclass on Classification, Structure, Amenability and Regularity
- From August 18th to August 22nd I am organizing the meeting of the String Geometry Research Network in Münster
- From July 20th to July 26th I will be visiting Marius Dadarlat at Purdue
- From June 16th to June 20th I participated in the workshop C*-algebras and Dynamical Systems during the thematic program on Abstract Harmonic Analysis, Banach and Operator Algebras at the Fields Institute, where I gave a talk about topological invariants of C(X)-algebras
- 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.

- 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.
