I obtained my PhD in Algebraic Topology (a fairly modern branch of Maths) in 2009, then worked in an investment bank as Quantitative Analyst while part-time teaching Topology at Open University. I am currently working in the financial services sector as a consultant on investment risk. I use Maths (especially undergraduate Maths) extensively in my job. I like discussing Maths and finance related topics with the likeminded. My current research interests are centred in Topological Data Analysis (TDA: http://en.wikipedia.org/wiki/Topological_data_analysis), on which you are especially welcome to get in touch.
