UCL Geometry & Topology

The UCL Geometry and Topology Group is part of the UCL Mathematics Department. We have nine faculty members, three postdocs and 14 PhD students. Our research interests include differential geometry and geometric analysis, symplectic geometry, gauge theory, low-dimensional topology and geometric group theory. We are involved with the London School of Geometry and Number Theory (LSGNT), a graduate program spanning UCL, King's College and Imperial.

Bellettini, Costante | c.bellettini | 710 | +44 (0)20 7679 2863 (Internal: 32863) |

I work in geometric analysis, with special emphasis on regularity questions arising in the calculus of variations and in calibrated geometry, often using methods from geometric measure theory and partial differential equations. I am particularly interested in the impact of such regularity results on questions arising in differential geometry. | |||

Homepage | arXiv | MathSciNet My work is in Differential Geometry, Partial Differential Equations and Geometric Analysis. I am especially interested in geometric flows (mean curvature flow, Ricci flow, Willmore flow etc), minimal surfaces and Willmore surfaces. | |||

Segal, Ed | e.segal | 605 | +44 (0)20 7679 3190 (Internal: 33190) |

My work involves algebraic geometry and homological algebra, with a lot of input from theoretical physics. My interests include derived categories, matrix factorizations, non-commutative resolutions, and topological field theories (mainly the B-model). | |||

Singer, Michael | michael.singer | 807a | +44 (0)20 7679 3190 (Internal: 33190) |

I have a number of interests in the differential geometry of special metrics and related geometric analysis. These include the study of Kähler metrics of constant scalar curvature and related questions about Bergman kernels and density functions; the geometry of self-dual and self-dual Einstein metrics in dimension 4; and also the application of analysis on manifolds with corners to geometric problems on singular and non-compact spaces. I am also interested in the geometry and topology of moduli spaces (for example of euclidean monopoles). |

Cioba, Alex | a.cioba.12 | ||

I am a student of Dr. Wendl. My interests revolve around low dimensional topology, more specifically symplectic and contact structures in dimensions 4 and 3. I currently work on understanding what the structure of moduli spaces of pseudo-holomorphic curves has to say about the global properties of these manifolds. | |||
