About Me
NEW! I am co-organising a Masterclass of Derived Category Methods in Ring Theory and registration is open! The masterclass is aimed at PhD students and postdocs.
I have been selected to be a member of the European Mathematical Society Young Academy, which promotes and supports early-career mathematicians across Europe.
Since Mar 2021, I have been a postdoc in the Aarhus Homological Algebra Group at Aarhus University, Denmark.
I was an LMS Early Career Fellow with support from Heilbronn (Dec 2020–Feb 2021) at University of Leeds.
I was a postdoc (Nov 2019–Nov 2020) at Newcastle University as part of the Higher Dimensional Homological Algebra project.
I completed my PhD, titled Partial cluster-tilted algebras via twin cotorsion pairs, quasi-abelian categories and Auslander-Reiten theory, under the supervision of Prof. Bethany R. Marsh at University of Leeds in 2019.
