Knauer, Kolja

I am a Ramon y Cajal researcher at UB since 2019. Before I was an associate professor at Aix-Marseille University. My research lies in the interaction of Algebraic and Geometric Combinatorics with a focus on Graph Theory, (Oriented) Matroids. and Algorithmics. I have answered questions and conjectures of Babai & Pultr, Barat & Thomassen, Biedl & Stern, Fukuda, Golumbic et al., Halman et al., Harutyunyan, Hochstättler, Saks & West, and Winkler.
