Dr Matthias Dörrzapf

MatthiasDr Matthias Dörrzapf is the Director of Scholarships & International Programmes. He is also the Director of Studies in Mathematics. 

Dr Dörrzapf has a PhD in Mathematics from Queens' College, Cambridge. Before he joined St. John's College he had a postdoctoral research position at the Lyman Laboratory of Physics at Harvard University. He obtained his undergraduate qualifications in Mathematics and Physics at the University of Karlsruhe

Dr Dörrzapf is interested in algebraic aspects of quantum field theories, in particular representations of symmetry algebras in conformal field theories and string theories. He has worked on the representation theory of superconformal algebras which plays a central role in string theory and has developed methods to classify superconformal representations. Dr Dörrzapf is also interested in probability theory and has worked on risk management models in financial mathematics in particular with respect to credit risk. He has done work for Deutsche Bank in Frankfurt and New York in collaboration with KMV corporation, San Francisco.

Dr Dörrzapf has lectured core courses such as Vector Calculus in Part IA and Symmetries and Groups in Phyiscs in Part II of the Cambridge Mathematical Tripos. For the College Dr Dörrzapf is teaching many of the core Part IA and Part IB applied mathematics courses.
