# Professor Tom Bridgeland

BA (Hons), PhD, FRS

Quondam Fellow since 2013

Professor of Mathematics, University of Sheffield

Tom Bridgeland has been working with homological techniques in algebraic geometry. He has completed his project with Ivan Smith relating quadratic differentials to stability conditions on certain three-dimensional Calabi-Yau categories. He is now studying derived categories of complex symplectic manifolds.
