Özgür Esentepe
Mathematician.
I am a postdoctoral fellow in the Institut für Mathematik at the University of Graz. I am interested in commutative algebra and representation theory. In particular, I like maximal CohenMacaulay modules and singularity categories.
Before coming to Graz, I was an EPSRC Research Fellow at the University of Leeds within the representation theory group. Before that, I was a postdoc at the University of Connecticut and I received my PhD from the University of Toronto under the supervision of RagnarOlaf Buchweitz. There I was a member of the Homological Methods Seminar and it shaped my research interests: representation theory, commutative algebra, homological algebra etc. After Ragnar passed away, I started working with Graham Leuschke while staying officially as a graduate student at the University of Toronto under the supervision of Joel Kamnitzer. I was an organizer of UCGEN and I used to live at AdIMOM.
