Editorial work
I am an editor for Annales de l’Institut Henri Poincaré D, a journal specializing in combinatorics, physics and their interactions. The journal is dedicated to publishing highquality original research articles and survey articles in which combinatorics and physics interact in both directions. Combinatorial papers should be motivated by potential applications to physical phenomena or models, while physics papers should contain some interesting combinatorial development.
I am an editor for Quantum, a nonprofit and open access peerreviewed journal that provides high visibility for quality research on quantum science and related fields.
I am an editor for Advances in Operator Theory, a journal that disseminates research papers featuring original findings, deep ideas, novel proofs, and profound influence in contemporary mathematical analysis, with a particular emphasis on operator theory and functional analysis.
I am an editor for Infinite Dimensional Analysis, Quantum Probability and Related Topics, which is a highly interdisciplinary journal, devoted to papers in infinite dimensional analysis and quantum probability with connections to classical probability, stochastic analysis, mathematical physics.
