Undergraduate Student in Mathematics, University of Warwick

About

I am an undergraduate student in Mathematics at the University of Warwick, with academic interests in quantum computing, mathematical foundations of machine learning, and combinatorial optimisation.

My current work focuses on using linear algebraic and structural methods to study problems in quantum information and machine learning, including stabilizer formalism, symplectic linear algebra and graph-theoretic optimisation.

This website collects selected essays, projects, notes, and academic materials.
