From October 2022 to October 2025, I was a doctoral candidate in Mathematics at the University of Göttingen. I worked under the supervision of Dr. Federico Vigolo and I was a member of the Research Training Group 2491: "Fourier Analysis and Spectral Theory".
In October 2025, I successfully defended my PhD thesis titled
"Generalised Diagonal Dimension and Roe-Like Algebras".
Research:
My research interests lie in the intersection of Coarse Geometry and Operator algebras. 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:
Roe Algebras
Nuclear and diagonal dimension of C*-algebras
(non-commutative) Cartan subalgebras
K-theory of operator algebras
(coarse) Baum-Connes conjecture
Warped cones
Expander graphs
