Education

Bridgeland was educated at Shelley High School[7] in Huddersfield and Christ's College, Cambridge, where he studied the Mathematical Tripos in the University of Cambridge, graduating with a first class degree in mathematics in 1994 and a distinction in Part III the following year. He completed his PhD[8] at the University of Edinburgh, where he also stayed for a postdoctoral research position.

Research and career

Bridgeland's research interest is in algebraic geometry, focusing on properties of derived categories of coherent sheaves on algebraic varieties.[9][10] His most-cited papers are on stability conditions, on triangulated categories[11] and K3 surfaces;[12] in the first he defines the idea of a stability condition on a triangulated category, and demonstrates that the set of all stability conditions on a fixed category form a manifold, whilst in the second he describes one connected component of the space of stability conditions on the bounded derived category of coherent sheaves on a complex algebraic K3 surface.

Bridgeland's work helped to establish the coherent derived category as a key invariant of algebraic varieties and stimulated world-wide enthusiasm for what had previously been a technical backwater.[3] His results on Fourier–Mukai transforms solve many problems within algebraic geometry, and have been influential in homological and commutative algebra, the theory of moduli spaces, representation theory and combinatorics.[3] Bridgeland's 2002 Annals paper introduced spaces of stability conditions on triangulated categories, replacing the traditional rational slope of moduli problems by a complex phase. This far-reaching innovation gives a rigorous mathematical language for describing D-branes and creates a new area of deep interaction between theoretical physics and algebraic geometry. It has been a central component of subsequent work on homological mirror symmetry.[3]

Bridgeland's research has been funded by the Engineering and Physical Sciences Research Council (EPSRC).[13]

Awards and honours

Bridgeland won the Berwick Prize in 2003, the Adams Prize in 2007 and was elected a Fellow of the Royal Society (FRS) in 2014.[3] He was an invited speaker at the International Congress of Mathematicians, Madrid in 2006.
