I obtained my Ph.D from Durham University in 2016 under the supervision of Matthew Johnson and Daniel Paulusma. Before coming to Charles, I was a postdoc at the University of Bergen and before that at Universite Paris Diderot.

My research interests include colorings and decompositions of graphs, combinatorial reconfiguration, combinatorial designs, extremal set theory and theoretical computer science.Contact info :
