I'm from Malaysia and I'm currently a postdoctoral fellow at the University of Sydney, working under Oded Yacobi and Geordie Williamson.
From 2022-2025 I was a postdoctoral fellow at the Institut des Hautes Études Scientifiques IHÉS.
I completed my PhD in 2022 at the Australian National University, under the supervision of Anthony Licata.
My research interest lies in the intersection of representation theory, category theory, topology and dynamics. More specifically, I'm interested in:
Categorification;
Coxeter and Artin--Tits groups;
quivers and algebras;
tensor and fusion categories;
Bridgeland stability conditions;
hyperplane arrangements; and
categorical dynamics.
See Research page for more info.

I have a few student projects around the following topics:
Coxeter groups and Coxeter groupoids.
Fundamental group(oids) associated to toric and/or hyperplane arrangements.
Algebras in fusion categories.
Feel free to contact me for more details.
Here are some works from my previous students:
Max Boyle (Honours): Constructing the Coxeter plane via fusion rings; link to thesis.
