Marcelo Aguiar is a Professor of Mathematics at Cornell University, specializing in Algebra, Combinatorics, and Category Theory. His research explores deep connections between algebraic structures and combinatorial objects, with a focus on Hopf algebras, their representations, and applications in combinatorics. Aguiar's work includes the study of pre-Poisson algebras, combinatorial Hopf algebras, and the structure of permutation and tree-based Hopf algebras. He has also contributed to the understanding of infinitesimal bialgebras, quadri-algebras, and the combinatorics of hyperplane arrangements. His research bridges abstract algebra with combinatorial enumeration, offering new insights into algebraic structures through categorical and combinatorial methods.
