Tenure Track Assistant Professor
MADALGO (Center for Massive Data Algorithmics)
Department of Computer Science
Velkommen, Benvenuto, Welcome!
In case you are confusing me with some other Chris Schwiegelshohn out there, I am the one working as a faculty member of the computer science department of Aarhus University.
I was previously working at Sapienza University. If you are a student with questions about one of my past courses, please contact me under <cschwiegelshohn"at"gmail.com>.
If you are not a former student of mine but want to contact me anyway, well it's the same email.
I work mostly on algorithm design. In particular, I like online, streaming, approximation and learning algorithms.
Publications you cannot find below you may be able to find at dblp or google scholar.
