Dr Panos Papazoglou

Fellow in Mathematics


I received my BA in Mathematics from the University of Crete and my PhD from Columbia University in New York. After that I held positions at the University of Warwick, at the University of Paris-Sud and at the University of Athens. I came to Queen’s in 2009.


I teach pure mathematics to first and second year students at Queen’s. I usually teach Linear Algebra and Groups, Fields and Rings to first year students and Group Theory, Fields, Number Theory and Multivariable Calculus to second year students.


I started my research studying Group actions on Trees. I moved on to Geometric Group Theory a relatively new approach to infinite groups whereby one treats groups as geometric objects. This led me to questions related to topology and geometry. Some specific topics that I studied are JSJ-decompositions of groups, isoperimetric inequalities both for groups and spaces and non-positively curved groups.
