My name is Florian Kurpicz and I am a postdoctoral researcher. I work in data structures and Algorithm Engineering in Prof. Dr. Peter Sanders’ Group at the Institute of Theoretical Informatics at the Karlsruhe Institute of Technology.

I received my PhD in Computer science from the TU Dortmund University in 2020, with a thesis on parallel text index construction under the supervision of Prof. Dr. Johannes Fischer.

I am working in Algorithm Engineering with a focus on Stringology (algorithms and data structures for textual data) and succinct data structures. On this website, you can read more about me and my research, find a list of my publications, check out my open source software, take a look at my talks, and see a list of courses taught by me.
