I am a second year PhD student in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge. My advisor is Ian Grojnowski and I am funded by the EPSRC. I am also a member of St John's College. |

Research |
My main interest is Algebraic Geometry, and I am particularly fond of the abstract side: I like homological, homotopical, categorical, simplicial and stacky things. The fact that I like them does unfortunately not imply that I know very much about them. Somewhere on the horizon lies the Geometric Langlands program. It is notoriously hard to describe what on earth Geometric Langlands is about, but David Ben-Zvi made an attempt in the LMS Invited Lectures 2007. My part III essay Cochains is a very short introduction to rational homotopy theory. It is mainly concerned with the theorem that "rational homotopy is very algebraic". In other words there is an equivalence of the homotopy category of (reasonably nice) rational spaces and certain commutative differential graded algebras called minimal models. |
Teaching |
In Michaelmas 2008 I was running pure maths examples classes for first years. Some information on these classes and first year maths in general can be found here.
Other courses I taught were Algebraic Geometry and Analysis II. I have also been group leader at the Part III Seminar Series, and talked in the Archimedeans' SU(2) series. (Here SU(2) is an acronym for "seminars for undergraduates, too".) |
Geometry Tea |
If you are a young geometer and around Cambridge on a Thursday afternoon around 3.30 pm there is Graduate Geometry Tea in the common room of pavillon E. There is always tea, often biscuits and usually an informal talk. Bring a mug.

Young Researchers in Maths |
From 16 to 18 April 2009 a unique event happened in Cambridge. For two days 200 young researchers from all areas of mathematics took over the CMS. Visit the website to reminisce or find out what you missed.
But Young Researchers in Maths is an ongoing project. Plans for Young Researchers in Maths 2010 are underway and any other ideas to improve links between young mathematicians are most welcome. Get involved here |
Quotes |
In celebration of the less serious aspects of the Cambridge math tripos here is a fine collection of lecturer quotes.
Some more gems can be found on these sites and another good source is the Imre Leader Appreciation Society. Some other sites have sadly disappeared (in particular one that collected the highlights of Matthias Dörrzapf's first Vector Calculus course). |
