Lluís Vena

Lluís Vena is a Research Fellow at the Polytechnic University of Catalonia (UPC), where he is a member of the GAPCOMB research group. His research focuses on extremal graph theory, Ramsey theory, graph polynomials, and additive number theory. He holds a Ph.D. from the University of Toronto (2014) and has held postdoctoral positions at institutions including Charles University in Prague and the University of Amsterdam.

Education:

• Ph.D. in Mathematics, University of Toronto, Canada (2009–2014)

Research Interests:
Lluís’ work explores combinatorial structures with an emphasis on extremal problems, Ramsey-type phenomena, and algebraic approaches to graph theory. He investigates properties of graph polynomials (e.g., Tutte polynomial), hypergraphs, and additive configurations in groups.

Publications: His recent work includes studies on Kruskal-Katona extremal families, graph embeddings on surfaces, and Ramsey degrees in hypergraphs. These contributions bridge discrete mathematics with topological and algebraic methods.

Collaborations: He has collaborated with researchers such as O. Serra, A. Goodall, and J. Nešetřil on topics ranging from graph homomorphisms to additive combinatorics.

Labs/Teams: Active member of the GAPCOMB group at UPC, focusing on combinatorics and graph theory research.
