Little about myself/my interests:

Classification of $C^*$-algebras and $*$-homomorphisms.
KK-Theory, connectivity and unsuspended E-theory, Cuntz semigroups.
Approximation and dimension theory; quasidiagonality. $W^*$-algebras.
Graph $C^*$-algebras and path groupoids. Groupoid modeling of $C^*$-algebras.
Higher category theory. $\infty$-categories and homotopy theory.

• Semigroups: Analyticity

• Reducing Spaces: Domain

• Abelian Algebras: Generator

• Normal Operators: Superalgebra

• Spectral Measures: Completeness

• Reinventing the Wheel: Lebesgue

• Uniform Spaces: Completeness
