About Me

I am a Ph.D. student in Computer Science at TU Wien working with Stefan Neumann.

I’m working on sublinear and streaming algorithms, with a focus on subgraph counting problems and their applications.

Previously, I earned my Master’s degrees in Mathematics and Computer Science from the University of Bonn.
