A massive congratulations to David O’Sullivan for winning the LSESU Teaching Award for Student Voice Champion 2026! 🏆

We are incredibly proud to have you in our department and can’t wait to see what you achieve next. Here’s to many more awards in the future! ✨

It was a pleasure to have Benny Sudakov, (ETH Zurich) Visiting Professor in our Department, speak at yesterday’s CGO seminar.

His talk explored an analogue of the classical Helly theorem for Hamming balls of bounded radius, establishing a Helly number that is independent of the ambient dimension, with connections to extremal set theory, coding theory and graph theory.

The work is joint with Noga Alon and Zhihan Jin.

A huge thank you, Professor Sudakov, for a brilliant talk! 💫

Yesterday our department welcomed 𝙋𝙧𝙤𝙛𝙚𝙨𝙨𝙤𝙧 𝙂é𝙧𝙖𝙧𝙙 𝘾𝙤𝙧𝙣𝙪é𝙟𝙤𝙡𝙨, (Carnegie Mellon University) who presented his latest work on computing nonnegative dyadic solutions to systems of linear equations.

The talk introduced algorithmic refinements that significantly improve solution sparsity, with computational experiments spanning random 0-1 systems, MIPLIB instances and perfect matching covering problems.

This research is joint work with Anthony Karahalios and Vrishabh Patil.

Many thanks to Professor Cornuéjols for a fascinating seminar! 🌟

Congratulations are in order!

It is a pleasure to spotlight Vanessa Madu, Guest Teacher in Mathematics at the LSE Department of Mathematics, who is among the winners of the STEM Educator of the Year Award!

Awarded by SheCanCode, Vanessa has been recognised for fostering inclusive classrooms where students feel empowered to explore complex ideas without fear. Beyond the university, she is a dedicated science communicator, bringing the "magic" of mathematics to life through outreach programmes—from lecturing at the Royal Institution to inspiring underrepresented students at summer schools.

Thank you, Vanessa, for your passion and commitment to showing the world that mathematics is truly transformative! 🚀

Check out our latest blog post with Jacob Calvert, a visiting fellow in the LSE Department of Mathematics. In this interview, Dr Calvert discusses his unique transition from bioengineering to complex systems research.

Additionally, he also shares insights into emergent behaviour, Markov chains, and the power of visual storytelling in academic communication.

We are delighted to share that Mathematics student 𝘼𝙖𝙠𝙖𝙧𝙨𝙝 𝘿𝙚𝙚𝙥𝙖𝙠 𝘽𝙤𝙨𝙬𝙖𝙣 will be presenting at this year’s Knowledge Beyond Boundaries, LSE’s interdisciplinary student research conference, taking place on Wednesday 17 June.

Aakarsh will present: ‘Who’s liable when no one’s driving? A three-pillar framework for AV accountability in Japan.’

The conference brings together our current students, recent alumni and students from CIVICA partner universities to showcase innovative research and explore this year’s theme, How to Save the Planet.

We’re incredibly proud to see our students sharing their research and contributing to important conversations.

Congratulations Aakarsh, and best of luck with your presentation. 🌟

Reflecting on the 19th Colloquia in Combinatorics, we are delighted to have hosted another year of insightful discussions and collaboration 🙌

The 2026 edition, our nineteenth year, was a resounding success, bringing together our community for an outstanding programme of twelve talks showcasing the latest developments in combinatorics and related fields.

Our sincere thanks go to the organisers, Peter Allen, Julia Böttcher, Felix Fischer, Viresh Patel and Jozef Skokan for delivering such an excellent event 👏

We are also deeply grateful for the continued support of the British Combinatorial Committee, the London Mathematical Society, the Heilbronn Institute for Mathematical Research, and the UKRI/EPSRC Additional Funding Programme for Mathematical Sciences.

It was a pleasure to see so many of you there. We are already looking forward to what next year will bring!
