Paul Cahill is a scholar of 20th-century Spanish literature, focusing on poetry that engages with its social context(s) while maintaining an active engagement with language itself. His work has looked primarily at poets writing during the 1960s and 1970s (Jenaro Talens, Jorge Urrutia, Eduardo Hervás, Aníbal Núñez, José-Miguel Ullán) and poets born in the 1960 and 1970s (Antonio Méndez Rubio, Víctor Gómez, Arturo Borra). His current research explores the lasting interest inspired by the Holocaust in Spanish poets who have little or no direct connection to it and in some cases were born decades after the end of World War II.
