Profile

Rosanna came to Sheffield in October 1999 after three years as a Research Fellow at Jesus College, Cambridge. Her Theories of Vagueness, was published by Cambridge University Press in 2000. This book investigates the vagueness of natural language, asking such questions as what the logic and semantics of vague language are, and with what methodology we should construct and assess theories of vagueness. She defends a supervaluationist theory of vagueness.

Rosanna's main philosophical interests lie within the philosophy of logic and language and metaphysics. She is currently working on issues concerning logical consequence
