  This is a survey article featuring some of Wolmer Vasconcelos contributions
to commutative algebra, and explaining how Vasconcelos' work and insights have
contributed to the development of commutative algebra and its interaction with
other areas to the present. We show that the regularity of subrings of normal
$k$-uniform monomial ideals is a monotone function, and we give a normality
criterion for edge ideals of graphs using Ehrhart rings.
