Doctoral Student in Mathematics at the University of Göttingen, working under the supervision of Dr. Federico Vigolo. Member of the Research Training Group 2491: "Fourier Analysis and Spectral Theory".

My research interests lie in the intersection of Coarse Geometry and Operator algebras. During my PhD project, I am interested in the K-theory of Roe algebras, which are C*-algebras associated with metric spaces and capture the large scale geometry of the space. More precisely, I am focused in the Roe algebra of Warped Cones, spaces which may be used to construct examples that violate the coarse Baum-Connes conjecture.
In addition, I am interested in the diagonal dimension of Cartan subalgebras in C*-algebras and their connection with coarse geometry.

Research interests:

• Coarse Geometry
• Nuclear and diagonal dimension of C*-algebras
• (non-commutative) Cartan subalgebras
• K-theory of operator algebras
• (coarse) Baum-Connes conjecture
• Warped cones
• Expander graphs
