Dan Ciubotaru
Diana Brown Fellow & Tutor in Pure Maths; Professor of Mathematics
My research is in representation theory, an area of mathematics concerned with the study of symmetries.
I am particularly interested in unitary representations of reductive Lie groups and Hecke algebras in the framework of the local Langlands correspondence.
My research has been recently supported by the EPSRC grants “New Horizons” EP/V046713/1 (1/2021-12/2023) and EP/N033922/1 (09/2016-08/2020).
At Somerville, I teach Prelims and Part A Pure Maths tutorials. In 2017, I was awarded an MPLS Teaching Award. I am currently the Academic Lead for Prelims and Part A in the Maths Institute.
