Research: I am interested in algebra, especially Rota-Baxter algebra, and its applications to number theory, mathematical physics, operads and combinatorics. For a brief discussion of Rota-Baxter algebra, see WHAT IS a Rota-Baxter Algebra, Notice of Amer. Math. Soc. 56 (2009), 1436-1437. For a more detailed introduction, see the book An Introduction to Rota-Baxter Algebra, International Press and High Education Press. See also A Page on Rota-Baxter Algebra for a list of related references.

Publications: Find my papers posted on the arXiv. Take a look of my ResearchGate profile. See below for a selected list of publications.
