Julian Holstein


	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.
Teaching	I am currently supervising Algebraic Geometry. 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. Previously I supervised Analysis II. I have also been group leader at the Part III Seminar Series, and given talks in the Graduate Geometry Chat and in the Archimedeans' SU(2) series. (Here SU(2) is an acronym for "seminars for undergraduates, too".)
Mirror Symmetry	One a week the Homological Mirror Symmetry Student Seminar meets. Do send me an email if you want to be on the mailing list for this. You are also welcome to just turn up.
Beyond Part III	From 16 to 18 April 2009 a unique event will happen in Cambridge. For two days young researchers from all areas of mathematics will take over the CMS. All mathematicians at the beginning of their research career are most welcome. Visit www.beyondpartiii.org to find out more. There is also a facebook group.
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).
