I'm a PhD candidate at the University of Victoria in BC, Canada, working with Prof. Heath Emerson and Prof. Marcelo Laca. My research is concerned with C*algebras, and right now I am particularly interested in KKtheory and noncommutative Poincaré duality.
From 2008 until 2011, I studied at the WWU
Münster and eventually wrote my BSc thesis under supervision of
Prof.
Siegfried Echterhoff.
Subsequently, I was at the GAU
Göttingen until 2014, where I wrote my MSc thesis on measurable
group actions by correspondences (that is, measurable Fell bundles) under
supervision of Prof. Ralf
Meyer.
If not on campus, chances are, I'm at the climbing gym. But sometimes, I paint, craft, do yoga, listen to audio books, or play the piano.
Here is my CV.
