I am currently studying for the DPhil degree in mathematics at the University of Oxford. My supervisor is Professor Stuart White. On November 2022, I completed the MSc (Mathematics and Statistics) degree at the University of Melbourne under the supervision of Professor Arun Ram.

On this website, you will find my CV and a selection of typed documents on a variety of mathematical topics.

I find a wide range of mathematics interesting. Broadly speaking, my research is on C*-algebras and operator theory. Specifically, I am very interested in graph C*-algebras, nuclear dimension and the Cuntz semigroup. Please refer to the notes I host on this website in order to see the kinds of mathematics I have studied.

My CV is here.

My notes on mathematics are here.

My preprints and publications are here.
