A photo of me

I am a maintainer of SciPy, an open source Python library providing fundamental algorithms for science and engineering, and Pixi, a cross-language, cross-platform package manager. See Open Source Software.

I am also a First Class MCompSciPhil graduate from the University of Oxford, having received The Hoare Prize for best overall performance in Computer Science and Philosophy 2026. See Oxford.

My pronouns are he/him.

Open Source Software

I have spent a lot of time contributing to free and open source software. This type of software is valuable because it democratises access to computational tools and encourages reproducible science. Also, anybody is welcome to help make it better.

Projects

Maintainer, Steering Council Member
I am a maintainer and steering council member of SciPy, one of the most widely used software libraries for science and engineering.
Core Maintainer
I am a core maintainer of Pixi, a cross-platform, cross-language package manager, written in Rust, built on top of the conda ecosystem.
Member
I am a member of the Consortium for Python Data API Standards, working on the Python array API standard.
Author
I am the primary author of array-api-extra, a library housing extra array-agnostic functions built on top of the array API standard.
Contributor
I have contributed to various other projects, mostly in the Scientific Python ecosystem and related ecosystems.

Positions

I have held the following tangible positions in this space:

Mentee (European Summer of Code)
I developed and maintained Pixi, a cross-platform, cross-language package manager, written in Rust, built on top of the conda ecosystem. I co-wrote this blog post.
Intern
I worked on interoperability in the Scientific Python Ecosystem, with significant contributions made towards SciPy’s support for the array API standard, under the mentorship of Dr Ralf Gommers, Dr Pamphile Roy, and Dr Irwin Zaid. I wrote this blog post.

Conferences

I have enjoyed attending various conferences to meet other developers and speak about my work. See talks for slides of my talks.

Speaker
I gave a talk titled ‘Instrumented CPython builds with Pixi’ at the EuroPython 2026 Packaging Summit in Kraków, Poland.
Speaker
I gave a talk titled ‘LinearOperator: stories from advancing an 18-year-old data structure in SciPy’ at EuroSciPy 2026 in Kraków, Poland. I also gave a talk with Wolf Vollprecht at the same conference, titled Pixi: better developer experience for scientific Python projects.
Speaker
I gave a talk titled ‘A Hitchhiker’s Guide to the Array API Standard Ecosystem’ in Paris, France.
Speaker
I gave a talk titled ‘A Hitchhiker’s Guide to the Array API Standard Ecosystem’ in Kraków, Poland.
Speaker
I gave a talk about my work on ‘The Array API Standard in SciPy’ in Szczecin, Poland.
Project Representative (SciPy)
I represented SciPy in discussions with developers across many NumFOCUS projects in Cambridge, Massachusets.

Oxford

I studied Computer Science & Philosophy at Christ Church, University of Oxford, and graduated with a First Class MCompSciPhil in 2026.

I was the Undergraduate Vice-President at Christ Church in 2024/25.

Prizes

I was awarded the following prizes:

Courses

I wrote a Computer Science dissertation titled ‘Batched and Hardware-Accelerated Iterative Sparse Linear Solvers in Python’, supervised by Professor Joe Pitt-Francis and Dr Irwin Zaid.

I studied the following Computer Science courses:

Discrete Mathematics, Probability, Linear Algebra, Continuous Mathematics, Design & Analysis of Algorithms, Models of Computation, Algorithms & Data Structures, Functional Programming, Imperative Programming, Concurrent Programming, Computer Security, Artificial Intelligence, Machine Learning, Quantum Information

under Dr Irwin Zaid, Professor Yarin Gal, Professor Lars Kunze, Dr Andrey Kravchenko, Dr Graham Benham, and Dr Murad Banaji.

I studied the following Philosophy courses:

General Philosophy, Turing on Computability and Intelligence, Early Modern Philosophy (Descartes & Hume), Ethics, Elements of Deductive Logic, Philosophical Logic, Feminist Theory, Ethics of Artificial Intelligence and Digital Technology, Theory of Politics

under Dr Fabian Pregel, Professor Peter Millican, Dr Aylon Cohen, Emily Dyson, Dr Christopher Frugé, Dr Alesia Priete, Dr Nick Tasker, Dr Theodor Nenu, and Dr Thomas Mitchell.

Positions

In my college, I held the following positions:

  • Undergraduate Vice-President
  • Undergraduate Access Officer
  • Access Tutor
  • Captain of the Men’s Football 2nd XI

My LinkedIn contains descriptions of these roles.


Career Interests

I am open to opportunities in the fields of Computer Science and Software Engineering, as well as their intersections with Philosophy, Politics, and Music.

I would be particularly interested in any opportunities to apply my skills to empower workers and grassroots community organisations in the face of corporate hell.

Other Interests

In my free time, I enjoy contributing to free and open source software, listening to music, running, playing football and pool, and video games.

I am broadly interested in politics, particularly in politics which aims to reduce inequality, increase democracy, and foster peace.
