ZhouningxinWang

I am now a lecturer at School of Mathematical Sciences, Nankai University in Tianjin, China.  I obtained my Ph.D. at IRIF, Université Paris Cité on May 24th, 2022, under the supervision of Reza Naserasr. I mainly work on colorings, flows, and homomorphisms of graphs and signed graphs.
